When The SimpsonsOpening Sequence was reanimated for its conversion to high definition in 2009, initially, during the screen showing the title, only one gag was used: a three-eyed crow would fly by it. Starting with Season 21, the gag would become a changing gag for each episode just like the billboard gags, the chalkboard gags, and the couch gags. There is also a title screen gag in the movie.
Instead of the usual music of the choir singing "The Simpsons," the "Miss Gulch/Wicked Witch of the West" theme from the 1939 film The Wizard of Oz is heard as Agnes Skinner rides her bicycle across the title.
A helicopter flies by, towing a banner that reads: "We don't hate you, Fox News. We just love MSNBC, CNN, CBS, NBC, ABC, PBS, BBC, ESPN, and Al Jazeera more." (Note: this title screen gag begins before the intro starts, meaning that the first frame of the intro is still when the helicopter and the first half of the banner appears, and when the second half of the banner appears, the intro begins playing).
Homer, dressed as Santa Claus, flies by in Santa's sleigh and exclaims, "Ho, ho, ho!" with Santa's Little Helper and Snowball V as reindeer with fake reindeer antlers on their heads and are restrained to the sleigh, and Stampy trailing behind with his trunk hanging onto the back of the sleigh.
O'Reilly the Leprechaun and the Easter Bunny jump up while O'Reilly yells in his scat talk. When they begin to fight in midair, they punch themselves together, causing them to disappear with dozens of clovers and easter eggs falling from where O'Reilly and the Easter Bunny disappeared.
The letters of the title card zoom in towards the screen, and the camera goes through the "P" in "Simpsons", just like how the title card was from seasons 1 to early season 20 prior to the idea of the title card gag.
A three-eyed crow flies by in a dark and spooky version of the clouds while a rusty version of the title card zooms in slower than normal and a creepy female chorus sings, "The Simpsons...". The three-eyed crow suddenly gets zapped by lightning and turned into a skeleton. Then, the crow falls down and the letters crumble and fly out of the screen.
Barney Gumble, dressed as Santa Claus, flies by in Santa's sleigh along with six of Santa's reindeer, and Santa's Little Helper as Rudolph in a snowy version of the clouds as the first six notes of the chorus to "Jingle Bells" plays. After Santa's Little Helper and the reindeer go off screen, Barney belches as he flies off.
This gag is themed after Minecraft, like the couch gag that follows, with "SIMCRAFT" in the Minecraft font with the "A" as a Creeper instead of "The Simpsons". The three-eyed crow, in Minecraft form, flies across the screen in a Minecraft-themed version of the clouds as a robotic chorus sings, "Simcraft...". After the crow leaves, the yellow splash text from the game appears on the bottom right of the logo and says "Parodies are easy!"
Because the episode is a crossover between The Simpsons and Futurama, this title screen gag is themed after the Futurama title screen. It starts off with the same blue light appearing like in Futurama, but after the Futurama theme starts playing, when the Planet Express ship forms the logo, it says "Simpsorama" in the Futurama font instead of "The Simpsons". The caption at the bottom says "A show out of ideas teams up with a show out of episodes".
Similar to the gag from SABF01, but this time, it's The Rich Texan wearing a Santa hat and flies by in his car, along with bulls that are restrained to the car as the first line of the verse to "Deck the Halls" plays. When the bulls are seen on screen, one of them bellows, and when The Rich Texan appears, he shouts, "Yee haw!" and shoots his guns.
This gag is themed after the Simpsons Pixel intro and couch gag that follows. It starts off with 16-bit versions of the clouds while a synthesized version of the "Ahh" choir plays, and the 8-bit title card letters appear while a synthesized version of the male chorus singing "The Simpsons..." plays. The letters get bigger as they zoom in, and the camera goes through the "P", starting the rest of the Simpsons Pixel intro.
Homer is seen inside his designed car, The Homer, and when the title card letters start to fill up the screen, The Homer's wheels store themselves, transforming into a hover car version of it, and it speeds off.
Similar to the gag from LABF20, but this time, Ralph Wiggum is wearing red shorts and a shirt that looks similar to Charlie Brown's shirt, the kite is orange, and shouts, "Take that, kite-eating tree!" as he glides from left to right.
A cupid flies across the screen holding a flag that reads, "SEASON FINALE", but a green dragon appears and breathes fire at the cupid, causing both it and the flag to catch on fire and fall in ashes. The dragon then flies off.
Abraham Lincoln and George Washington are flying towards each other on hot air balloons with Lincoln's balloon colored red and reading, "Vote Lincoln", and Washington's balloon colored blue and reading, "Vote Washington". They then collide with each other, causing the hot air balloons to explode.
