As the standard theme music stops, the family forms a chorus line, joined by a line of Rockette-like women, all high-kicking to a Vegas-like rendition of the main theme melody. The living room walls are lifted to make way for a large production number, featuring hand-standing elephants, magicians, Santa's Little Helper leaping through a ring of fire, and more all set to circus style music. The standard theme music then returns, concluding normally. (This is the first extra-long couch gag, as well as the first to cut into the standard theme with alternate music. This couch gag is also used for edited versions of other episodes from all seasons.)
The Simpsons sit down, followed by three rows of secondary characters (such as Kent Brockman, Apu, Krusty, Principal Skinner, Marge's mother Jackie, Mr. Burns, Smithers, a black-haired Princess Kashmir in her belly dancer costume, Nelson, Milhouse, Martin, and Mrs. Krabappel) from the show who obstruct the family's view.
A director does three couch gag takes. Take one: The Simpsons first run into the living room and shatter like glass, with Santa's Little Helper walking in to look at the mess on the floor. Take two: The Simpsons run in and coalesce into a multicolored, five-headed blob. Take three: The Simpsons run in and explode on contact, with Maggie's pacifier falling onto the blackened crater. (syndicated reruns use the “take one” couch gag only and takes two and three are used as individual couch gags in different episodes)
The Simpsons sit on the couch just as a translucent FOX station identification logo appears in the lower right hand corner of the screen. Homer notices it, gets up from the couch, peels it off, and stomps on it (with the family joining him in stomping it) before returning to the couch.
The living room is at the center of an M.C. Escher's Relativity style environment with multiple staircases and conflicting perspectives; the family enters from various directions (and dimensions) and sits.
Homer, Marge, Bart, Lisa, Maggie, Grampa (who’s sleeping), Santa's Little Helper, and Snowball II are in a Brady Bunch-style nine-square grid, with the couch in the center square. Everyone (except Grampa) runs to the center square.
The whole scene is a Simpsons rendition of The Beatles' Sgt. Pepper album, featuring a large crowd of regulars, several objects associated with the show, wax statues of the Simpsons as they were on The Tracey Ullman Show. The last chord to the Beatles song, "A Day in the Life" plays instead of the traditional Simpsons music as the family comes in, standing front and center and dressed in Sgt. Pepper regalia. Homer looks around and turns to look at the crowded scene behind him.
The family sits down, but now Bart is green. Homer fiddles with the TV antenna and Bart changes to red. Homer then returns to the couch, and smacks Bart in the back of the head in order to return him to his normal color (yellow).
The couch is now a giant Whack-A-Mole game, with the Simpson family as the moles. The clown hallucination music from “Homie the Clown” plays as an unseen player tries to hit one of the Simpson moles — and successfully gets Homer.
The living room is in an “America Onlink” window on a computer screen. An unseen computer user tries to download the family, but the download shows no signs of progress after a few seconds and the user tries to exit the window (which also doesn’t work).
The couch is on the deck of a ship at sea in rough waters, sliding back and forth with the tilt of the ship. The family, dressed in rain gear, sits on the couch, before an enormous wave washes them away. The TV surfaces moments later.
The family comes in, dressed as the Harlem Globetrotters, passing a basketball to each other while Sweet Georgia Brown plays. Maggie dunks the ball into the basket above the couch, hitting Homer on the head.
Homer runs in alone and stands in front of the couch. The top half of him pops off and on to the couch revealing a smaller Marge standing inside the lower half of Homer, like a Russian nesting doll. The top half of Marge pops off revealing Bart, whose top half pops off revealing Lisa, whose top half finally pops off to reveal Maggie, who stays in the middle of Homer’s body and sucks on her pacifier.
The Simpsons sit on the couch as normal. The camera zooms out and reveals that the living room is part of a snow globe that two hands shake to make the snow fall. (Christmas episode for this first usage)
The floor is a treadmill. Marge, Lisa, Bart, and Maggie run in place for a few seconds, then successfully dismount, while Homer gets stuck on it, yelling, "Marge, stop this crazy thing!" a la George Jetson in the original closing credits of The Jetsons.
Similar to the couch gag on "Homer's Triple Bypass", the Simpsons are minimized and trying to get on the giant couch. Unlike the couch gag to "Homer's Triple Bypass," The Simpsons take a little longer to climb onto the couch and, once they reach the top, Santa's Little Helper grabs Homer and carries him away in his mouth.
The Simpsons are frogs (with Maggie as a tadpole) jumping to a lily pad "couch. Homer turns on the TV with his tongue. (according to the Season 9 DVD commentary, Dan Castellaneta's daughter came up with the idea for this couch gag)
A vine growns in the middle of the living room and sprouts into a tree bearing Simpsons family versions of various fruits and vegetables: Bart is a strawberry, Homer is a squash, Marge is an asparagus, Maggie is broccoli, and Lisa is a pineapple.
In a parody of the Rocky & Bullwinkle bumpers, The Simpsons fall off a cliff during a lightning storm as the Rocky & Bullwinkle theme plays throughout. Their eyes are shown floating towards the heavens. The scene then cuts to The Simpsons sprouting from the ground amidst a garden of flowers. Bart spits up a clod of dirt.
The Simpson family find themselves in Mrs. Krabappel's classroom where Bart is writing the blackboard punishment phrase, "I will not mess with the opening credits," making a chalkboard gag within a couch gag.
Similar to the couch gag in Marge vs. the Monorail, the living room is filled with supporting characters from the show. Unlike "Marge vs. the Monorail," the living room is now a movie theater and the Simpsons are shuffling their way through to find a seat. After they sit down, Homer leans in and eats from the Comic Book Guy's popcorn tub.
The family never makes it to the couch; Bart falls off of his skateboard. Lisa gets catapulted into the garage roof, and Homer gets run down by Marge(with Maggie next to her as they honk horns) as she drives into the garage. Meanwhile, in the living room Freddy Krueger (of the A Nightmare on Elm Street movies) and Jason Voorhees (of the Friday the 13th movies) sit on the couch, wondering where the family is.
The family sits. Salon-style hair dryers descend onto their heads, then lift up, revealing the family members all have swapped hairdos. Homer has Maggie's spikes, Marge has Bart's spikes, Bart has Lisa's spikes, Lisa has Homer's "combover," and Maggie has Marge's big, blue bouffant (the weight of which causes Maggie to fall off the couch).
In a parody of the famous scene in Dr. Strangelove where Slim Pickens’s character rides the bomb, the Simpsons (wearing white cowboy hats) straddle the couch, which sprouts a point on its back (pushing away the side table) and is dropped from a trap door in the floor. The Simpsons scream, “Yahoo!” as they plummet into oblivion.
The living room is in shallow water and the Simpsons sit on the couch. When an iceberg floats by, the couch sinks vertically like the RMS Titanic and the family clings to dear life as it goes under. Maggie resurfaces on a couch cushion moments later with the remote control in hand.
The family comes in. Marge notices Matt Groening's signature at the bottom of the screen and wipes it off. A caricature of Matt Groening (complete with graying beard, glasses, and a tacky orange and yellow Hawaiian shirt) comes in and resigns the scene.
The family members (mostly) appear as they have in previous Halloween episodes: Homer is a jack-in-the-box (from II), Bart is a mutant fly (from VIII), Marge is a witch (also from VIII), and Maggie is an alien (from IX); Lisa, an ax murder victim (the only one not based on a previous episode), comments on the lackluster Halloween special hosted by Kang and Kodos ("What do aliens have to do with Halloween?"). Maggie yells, "Silence!" (in Kang's voice) and blasts Lisa with her ray-gun.
The living room is set up like a trendy nightclub (complete with a disco ball, a velvet rope, three 20-something club hoppers, and a bouncer). The bouncer lets Marge, Lisa, Bart, and Maggie in, but sends Homer away.
The Simpsons sit on the couch and the wall spins around as seen in "Homer the Heretic." Instead of an empty couch, however, a Vincent Price-esque mad scientist and a shackled and scared Ned Flanders are on the other side of the wall.
A crash test dummy version of the family sits. The couch slides forward and slams into the TV (simluating a car crash test), then pulls back into place. Crash test dummy Homer's head falls off from the trauma.
The Simpsons (save Maggie, who is in Marge's arms) are barefoot and briskly walking across a bed of hot coals. When the family sits on the couch, they prop their feet up, revealing their black and smoldering soles.
Marge, Bart, Lisa, and Maggie (dressed in jungle loincloths) swing into the room on a vine gracefully like Tarzan. Homer, however, swings by, fails to release the vine in time, and crashes offscreen like George of the Jungle.
Bart puts a whoopee cushion under Homer's spot. When the family sits down, Homer sits on it and triggers its farting sound. Homer grins sheepishly at Marge, Lisa, and Maggie (who are frowning) while Bart laughs.
The shot opens on the TV rather than the couch. The family runs in and freezes in mid-air. The camera pans around them in Matrix-style bullet-time. When the camera is angled on the couch, time resumes normally and they sit down without further incident.
A skating ramp is set up next to the couch. Marge (with Maggie in hand), Bart, and Lisa successfully do skateboard tricks off the ramp and onto the couch. Homer, however, falls off the ramp and, adding injury to insult, gets hit on the head with his own skateboard.
Santa’s Little Helper dances on his hind legs like Snoopy on A Charlie Brown Christmas while a Peanuts-esque piano riff plays. When the family comes in, Santa’s Little Helper slowly stops dancing, sits on his hind legs, and barks.
A football is thrown in the center of the living room. The Simpsons, dressed as football players, tackle each other for the ball. Maggie squirms out with the ball in hand, spikes it, and does a victory dance while squealing with delight.
The couch is replaced by a valet parking spot. The Squeaky-Voiced Teen pushes a couch in place for the Simpsons to sit down. He then holds his hand out for a tip and leaves angrily when he doesn’t get it.
The Simpsons are in the simplistically drawn sailboat painting located behind the couch. They jump out of the painting by going in the "water". The living room is wet from the splash and Homer uses his finger to clean his ear out while clicking on the TV with the remote.
The Simpsons sit on the couch as normal. A crane game clamp comes down and picks up Homer. Homer screams, “Ow! My brain!” as he's being pulled out of frame. (Some later airings have Homer screaming in pain)
The family runs in to find the Blue Man Group performing on drums in front of the couch. Homer murmurs "What the-?!" (in reruns and repeats of this couch gag in other episodes, The Blue Man Group plays more aggressively and Homer's "What the--?!" is muted out)
Homer is on water skis, with the others on him, as he ski-jumps over sharks; everybody lands on the couch, but Homer is without his legs, which are in the sharks' mouths. Homer doesn't notice (a reference to the term "jumped the shark", describing a TV show that has reached its peak and is now declining in quality or has done something to cause it to decline prematurely).
In a parody of the Macintosh paint program, Kid Pix, a mouse cursor drags Homer from the left side of the couch to the right, changes the wall color to green, and replaces the boat painting with the Mona Lisa. (Final couch gag to be traditionally animated)
The family sits on the couch. Homer clicks on the remote control and sends the family to the Stone Age, clicks it again to send them to the Roman Empire where they watch a gladiator match, and clicks it a final time to return them to the present. First couch gag to be digitally animated)
In black and white, the Simpsons are wearing early-20th-century clothing and are watching the TV from a girder at a construction site. (Done in the style of Charles C. Ebbets' photograph "Lunch Atop a Skyscraper".)
The couch is a street bench in Japan, and everyone is a famous anime character: Homer is Ultraman, Marge is Jun from Science Ninja Team Gatchaman, Lisa is Usagi Tsukino, the protagonist from Sailor Moon, Bart is Astro Boy, and Maggie is Pikachu from Pokémon.
In a parody of Powers of Ten, the couch scene pans out until it reaches outer space, where the galaxies are replaced with atoms, which pan out until they reach Homer's head and then the couch scene again. Afterwards, Homer says, "Wooowwww." (reairings and repeats of the couch gag in other episodes redub "Wooowww" with "Cool." or "Weird.", and have Kang and Kodos laughing instead of staying silent)
After the family takes their usual places on the couch, the couch rises into the air and is actually part of the tendril of an anglerfish (which bears a striking resemblance to the one from Finding Nemo), which eats the family.
The family runs into the room and take their usual places on the couch. Nothing happens, so Lisa then asks directly to the viewers, "What, can't we sit on the couch without something happening?" Homer then gets impaled by a spear and yells, "D'oh!"
The family, dressed as hockey players, with cuts and scrapes, skate into the living room and skate around the couch. Homer is carrying the Stanley Cup with Maggie sitting in the bowl. (There was a lockout in NHL that season)
The family enters the living room and sits on the couch like normal. "Homer" then pulls off his face, revealing himself to be Sideshow Bob. Bob pulls out a knife and chases Bart out of the living room. (Note that some airings use an alternate version where after Sideshow Bob grabs his knife out, Bart starts to panic and runs out of the living room screaming with no chase happening. Some airings use the Duplicate Family couch gag instead.)
The family sits on the couch, only to have a spit comes through the wall and the floor open up to reveal fire down below. The couch and family begin rotating over the fire like a kebab over a grill. Marge's hair catches fire and the boat painting falls off the wall.
Several toy forms of transportation come into the living room, only to change Transformers-style into the family. Homer is Optimus Prime, Marge is Skyfire, Lisa is Hound, Maggie is Bumblebee, and Bart is Jazz.
The living room is an almost fully assembled jigsaw puzzle, with only the pieces with the Simpsons' heads needing to be placed. The person completing the puzzle places all the heads on correctly except for Homer and Maggie, after which the person switches the two.
The family enters the living room through a metal detector, except for Homer, who sets it off. After three failed attempts, Homer (who is now stripped down to his briefs) is detained by a security guard who is inspecting Homer with a handheld scanning wand.
The family enters the living room and takes their places on the couch, then an on-screen TiVo style menu pops up asking if the viewer would like to delete or save this recording. "Delete this recording now" is selected and the screen goes blank.
The family runs in to sit on the couch, but it turns into a monster and chases them out of the house. Everyone's couches come to life and start attacking and swallowing the people sitting on them; after showing Hans Moleman, Grampa, Sherri, Terri, Eddie and Lou getting attacked by couches, Professor Frink is attacked by a futuristic flying couch with laser weaponry, and Moe is attacked by the booths in his bar, but fights quite well with his shotgun. Homer eventually takes shelter in a store called "Couch World", where he is piled upon by dozens of couches. (an unusually long couch gag, as it runs for exactly forty seconds)
The Simpsons sit on the couch as normal and a camera flashes, setting off a series of family portraits. In the 2006 and 2007 portraits, they all look the same. In 2008, Homer is missing, Marge is wearing black, and the kids are wearing their Sunday clothes. In 2009, Lenny has taken Homer's place and Bart and Lisa both begin puberty. In 2010, Carl has taken Marge's place and Lenny is still there. In 2011, Marge is back, but Lenny is gone and replaced by Jimbo Jones. In 2012, Homer is back, but is now a robot. In 2013, every member of the Simpson family is a robot.
In a parody of the Bonanza opening, a map of Springfield burns away to reveal the family on horseback in the countryside (The couch is nowhere to be found, however). The Bonanza-like music that plays continues over the TV credits.
The family enters the living room only to find out that their access to the couch has been blocked by laser beams. They work their way through the laser beams and sit down. Then, the beams shut off and Homer's head drops to the floor.
The family (played by live action actors) sit on the couch just before the TV credits come on, which is superimposed over the live action TV. (Syndicated airings have a repeat of the Kebab Grill couch gag instead)
The couch is replaced by four wooden stools. An instrumental of "Pop Goes the Weasel" plays as the family plays musical chairs. When the music stops, everyone, except for Homer, sits down. Homer groans in disappointment.
A vending machine is in place of the couch, which is filled with snacks that resemble Simpsons characters (including the Simpson family). Ralph Wiggum comes in, selects a Homer figurine, and bites the head off before leaving.
The family sits down and gets moved across the floor in a car wash, where they get sprayed with water, squirted with hot wax, and scrubbed with brushes. Marge's hair turns puffy, Maggie's pacifier goes missing, and everyone looks exhausted as three men wipe them dry and puts a new pacifier into Maggie's mouth.
The family (in Christmas attire) sits on the couch, and the camera pulls out to reveal they are in a Christmas ornament which is on their Christmas tree. Santa's Little Helper and Snowball V rest nearby as the last notes of a Christmas tune play instrumentally in the background.
Homer evolves from a single-celled organism which continuously divides to a more complex organism—first as a jellyfish, then a common fish that nearly escapes the clutches of an octopus that looks like Mr. Burns. Getting out of the ocean, Homer evolves into a prehistoric lizard that extends his tongue to snack on an insect that resembles his power plant coworker, Lenny. Homer then evolves into a slightly larger lizard with a scale on his back that sees a pterodactyl resembling Principal Skinner's mother, Agnes, flying overhead. Homer then evolves into a rat that gets chased by a tyrannosaurus rex resembling Bart, who then gets into a battle with a stegosaurus resembling Lisa. Homer hides in a hole just before a large asteroid crashes on Earth, wiping out all dinosaur life. Homer comes out of the hole, passing the skeletal remains of T-Rex Bart, before changing into a sloth, then a monkey as he approaches a jungle, becoming more apelike upon swinging through the trees. Leaving the jungle, a brief Ice Age occurs as he evolves from a Neanderthal, to a Cro-Magnon, to an upright walking caveman. Caveman Homer passes by Moe (who is also a caveman), who then devolves into a rat creature. As Homer continues walking, he evolves into men from different historical eras (a nomad from the Middle Ages, a Spanish explorer, a Pilgrim, and a 19th-century intellectual) until he finally evolves into his modern self and enters the house, stepping over Santa's Little Helper. With the rest of the family sitting on the sofa, Marge asks him "What took you so long?", but Homer can only give an exhausted sigh of relief. (This is the second longest couch gag to date as it runs over 1 minute long; the longest being the Rick and Morty Couch Gag from Mathlete's Feat)
The Simpson family comes in and sits on the couch. A second family comes and also sits on the couch. Eventually, hundreds of multiple families come in, and the whole house gets overflowed by them. One of the Homers shouts, "Hey, don't shove!"
The entire opening sequence is changed to show a ruined Springfield being rebuilt in the aftermath of The Simpsons Movie. As construction work goes on around them, The Simpsons join Plopper the pig on the couch to the tune of the "Spider-Pig" song. Homer holds him and says "My summer love", to which Plopper squeals in delight.
The living room is made of Lego bricks and the family members are built one by one out of Legos. Homer can be heard shouting, "Woo-hoo!" when a 1x3 Lego Brick is put on his head, and "D'oh!" when a black 1x1 Lego brick (representing his two strands) is placed on his head instead.
The family sits down as normal, except Maggie is missing. Homer looks to the empty space where Maggie is, then gets lifted by a giant Maggie as the camera pulls out to reveal the living room being part of a dollhouse and the family as the dolls that live within. Maggie puts the miniature Homer in her mouth and sucks it like a pacifier.
Wile E. Coyote paints a fake couch on the wall which the Simpsons run into, except for Maggie, who sticks her tongue out and takes off, Road-Runner style. The remaining family members sit on the couch except for Homer, who falls through the wall and yells,"D'oh!"
The Simpsons rush to the couch in 79 AD. Mount Vesuvius explodes and covers them in ash. (Possibly a reference to Pompeii where in the City of Pompeii in the Roman Empire, a volcano exploded very fast and killed people and covering them with ash)
The Simpsons go through the openings of The Honeymooners (from the 1950s), The Dick Van Dyke Show (from the 1960s), The Brady Bunch (from the 1970s), and Cheers (from the 1980s). In the Cheers segment, Sideshow Bob enters in reference to Kelsey Grammer's character in Cheers, the family run out screaming and end up at the couch in the opening of their show (from the 1990s/2000s) with a sigh of relief.
The Simpsons come in and find their couch beaten and torn. Funeral music plays as they bury the couch in the backyard. The Simpsons then visit a ranch to pick out a new couch. The Simpsons sit on a black and white spotted couch, which throws Homer off it. The Simpsons are now back in the living room, sitting on their new couch. Homer is in a body cast and turns on their wall-mounted flatscreen TV.
The Simpsons are a meal at a fancy restaurant (Homer is a garden salad, Lisa's face appears in a bowl of soup, Marge is a plate of spaghetti and meatballs, Bart is a T-Bone steak, and Maggie is the mint that comes with the restaurant bill), which Comic Book Guy eats. After he wipes his mouth with a napkin, a stain appears that resembles The Simpsons sitting on the couch.
The screen is white. A cartoon left hand flips an animation cell that has eyes on it, flips another that has Homer's skeleton sitting cross-legged, flips another that has Homer's stomach and a can of Duff beer on the lap, flips another that has Homer naked, another where the rest of the family are fully clothed and sitting in mid-air, and another where The Simpsons are in their living room and sitting on the couch. Marge notices Homer is still naked and pulls down an animation cell that has Homer's clothes.
The living room is covered in thick, jungle plants. The Simpsons slash their way through in order to reach the couch, and find an ape version of the Simpson family already seated. The ape-Simpsons hoot and screech, scaring off the human Simpsons.

A large marble rock is in the living room where the couch should be. A stereotypical French sculptor quickly chisels out a statue of The Simpsons sitting on the couch. The sculptor then turns the statue of the Simpsons into a statue of a Civil War soldier on a horse.
The Simpsons are at an underground train station where a train pulls in and opens its doors, revealing the living room, complete with couch. The Simpsons get in and sigh as the door closes and the train pulls off. (This couch gag is similar to the one from Missionary: Impossible, but from a different angle)
The Simpsons, dressed in prehistoric-style clothing, runs onto the couch (really a log, which is in a prehistoric area, resting on a tar pit) and sinks with it into a tar pit. Their skeletons, their prehistoric clothing and the log are all in a museum exhibit.
Instead of the couch, the Simpsons (dressed as Victorian-era Christmas carolers) appear next to a Christmas tree and sing a parody of "The 12 Days of Christmas," featuring twelve Grampas grumbling (as they stand in a customer return line), eleven Barneys belching (as they lie drunk in the snow), ten Lennys leaping (over a fence), nine Carls dancing (in a ballroom), eight Moes a-milking, seven Selmas smoking, six Flanders praying, five golden Frinks (Professor Frink's heads are on five gold coins), four crawling nerds (Database, Wendell, Martin, and Milhouse crawling from Nelson Muntz), three-eyed fish (Blinky), two special Ralphs, and (as the Simpsons walk to the couch), a Maggie in a Snuggly.

When electrocuted they scream and light up (the sign the family holds has the production number's code on it)
In a spoof of 2009's Avatar, the Simpson family are transferred into Nav'i bodies and each member try to get a "couch-monster", but only Bart manages to get it. The couch flies to a mountain, which Bart turns on the TV.

A few earlier couch gags appear at normal speed, then screenshots of the previous couch gags appear, right up until the gag from "The Daughter Also Rises". Afterwards, the Simpsons run to the couch as normal, look around, and then the screen zooms out to reveal the previous couch gags in a 25x20 mosaic saying "500". The screen then shatters, and shows Homer strangling Bart and says "Why you little!" (looking similar to the promo image for "Angry Dad: The Movie").
In a parody of the opening to "Game of Thrones", various structures rise from the ground via rolling gears, with the family and other characters dressed in medieval clothes.

In a parody of the Breaking Bad opening, Marge bakes cupcakes and Homer comes along and take some of the mixture. She puts the cupcakes in the oven and they rise. She then has a bake sale. Milhouse takes on and we see Homer watching through binoculars. Eventually, Walter White and Jesse Pinkman are watching the couch gag on their TV.
The Simpsons jump from a blimp and go sky diving. Everyone successfully pulls out their parachute except for Homer's that falls off. Homer then falls on everyone else and they crash land into the living room and destroy the couch.
Original/international (except Canada)/online airing: The Simpsons are dandelions. The TV blows on them, causing their seeds (which are actually the family members) to fly around the room.
Canada airing: A loon, a Canadian hockey player, John A. MacDonald and a beaver all sit on the Simpsons’s couch. O Canada (the national anthem of Canada) plays. The Simpsons rush in and shove them aside, but their guests say nothing. Maggie sucks on a hockey puck.
Just as it's seen in Season 11's "E-I-E-I-D'oh" and Season 22's "Elementary School Musical", the couch is roped off, this time in honor of the series' 25th season. A bouncer lets Marge and the kids sit on the couch and refuses to let Homer do so. In the end credits, the couch gag is continued with the bouncer letting everyone in Springfield in. The bouncer also lets the families from Family Guy, Bob's Burgers, American Dad!, and The Cleveland Show in (the latter after a brief protest of racism). Homer is still turned away, and is eventually tazed.
Guillermo Del Toro-style opening, with various references to horror and sci-fi monsters and movies. The gag ends with Lisa falling through a hole Alice in Wonderland-style and ending up in the ending sequence of Pan's Labyrinth (a Del Toro film), where she is hypnotized by the Hypnotoad from Futurama.
The Simpson family shows their version of the first Thanksgiving, where they (as Pilgrims) escape persecution by boarding the Mayflower (which looks similar to the sailboat in the painting that hangs above the couch). The Simpsons soon sail to Plymouth Couch (aparody of Plymouth Rock), where Apu (an Indian) offers them a Thanksgiving dinner for $19.95 a person.
Homer is watching the Super Bowl when he goes to get a pack of beer. Trouble is, Bart tossed the six-pack on an overhead power line. Homer goes to retrieve the six-pack, only to be eletrocuted and cause a power outage across Springfield.
The family rush to the couch as normal. Suddenly, the power goes out. Marge goes to fix the fuse, and when the lights come back on, the family is now drawn Triplets of Bellville-style, and everything has a French aesthetic to it. Bart plays with a do-it-yourself foie gras kit, Lisa plays an accordion, Marge searches for Maggie, and Homer goes to eat a snail off the TV, unaware that Maggie is stuck between his buttcheeks.
Homer is the patient from the board game "Operation." Other characters appear as the pieces, such as Lisa (who is Brainy (the brain)) and Moe (who is Elbow Bender (the elbow)). After the "Pain in the Butt" (Bart) is removed, he grabs the forceps and sticks in the side, making Homer buzz and shout, "D'oh!" as Bart laughs.
The Simpsons find Itchy about to kill Scratchy on the couch. Homer intervenes by removing Itchy and allowing Scratchy to stay on the couch for several months, which ultimately starts annoying the family. Homer brings back Itchy who effectively murders Scratchy.
The couch is a ski lift. The family walks in, ready to go skiing. The couch rises up. Seconds later, the couch comes back down and the family are all injured. Except for Maggie, who comes in and has a medal and isn't injured.
The family are playing with their smartphones as they walk in. But, they don't pay attention to where they're going and bump into each other and fall over. They pick up their smartphones and carry on playing.
In a parody of Disney's Frozen, there is a message that reads; “Now for obligatory Frozen reference”. Afterwards, the family tries to sit on a snow couch, where Lisa, as Elsa, is sitting. Bart hits her with a snowball and she immediately creates a giant ice palace, with Bart stuck at the top. Homer appears as Olaf, and bites his own nose, disappointed to discover it is simply a carrot.
A piano version of "Great Gate of Kiev" is played in the background as the gag showcases artwork of each Simpson. The camera turns to the Simpsons sitting at an art gallery. Homer grabs the remote control and all the artwork on the wall changes channels.
In a parody of Goldilocks and the Three Bears, Homer, Marge and Bart are shown walking into their home. They find out that someone has been eating their porridge and broke their couchs but they catch Lisa who is sleeping on Bart's couch. She wakes up to find the three of them surrounding her, causing a fight between them that ends with the Simpsons eating parts of Homer's body. The scene is revealed to be a story Homer told to a traumatized Maggie.
The Simpsons sit on the couch, only to be sucked into a portal. They come in again and the same thing happens two times more. The fourth time, Bart doesn't sit on the couch. As the rest of the family gets sucked in, Bart uses the remote to get rid of the portal. He sits down to watch television when he discovers and holds Homer's decapitated head.
In a gag written and animated by Rick and Morty creators Dan Harmon and Justin Roiland, the Simpsons sit down on the couch, but Rick and Morty suddenly crash their ship into the house, killing them. Panicking, Rick collects some of the family's gooey remains in a vial and sends Morty to have new Simpsons made while he cleans up the wreckage. While Morty travels to an alien world to get the materials needed to restore the family, Rick proceeds to ransack the Simpsons' home, stealing their possessions and freezing Ned Flanders. When Morty returns, Rick finishes the restoration process. However, because Rick cleaned the vial with his spit, the family members all resemble deformed versions of Rick. The two fly off, destroying the frozen Flanders in the process, and Bart declares "No more guest animators, man!"
The episode opens with a Kricfalusi-style animated short where the Simpson children are trick-n-treating before being set upon by soul-hungry spirits with a monstrous Frank Grimes among them. The spirits chase after the Simpson children to their house, with the Frank Grimes monster taking Homer's soul.
In a parody of the Disney short "Feast" (known here as "Fat"), Santa's Little Helper gets fed by the family until he becomes fat and is sent to the Springfield Retirement Castle, where he's fed strained prunes and dies afterwards. He is greeted by God. He sees the Fit Dog Heaven but God sends him to Fat Dog Hell where a signs says free pizza.
The couch leaves the family and they embark on an adventure to find their sofa. In the end, it is revealed that was a dream while Homer was sleeping on the couch. But then Marge leaves Homer for spending too much time in the couch.
In Bill Plympton's fourth couch gag, the television and the couch dreams of the television bouncing on the couch and both having fun. At the end of the dream, the television tries to bounce on the couch but gets prevented by the plug and it falls on the floor.
Homer sends a message with emoji of him, Marge, Bart, Lisa, Maggie and the couch, and recieves in answer "Meh" "I don't get it" "Needs a payoff" "Created by Matt Groening", to which he says "Oh, sorry, yes sir", and "Developed by James L. Brooks Matt Groening Sam Simon", to which he says "Who are this guys?", and the reciever sends "Meh" again.
