The Rick and Morty Couch Gag is a couch gag that was used in the episode Mathlete's Feat in which Rick and Morty from Rick and Morty crash through the wall and kill The Simpsons.
The Simpsons rush in and sit on the couch as normal. Suddenly, a space cruiser crashes through the wall, the Simpsons screaming as they are reduced to yellow smears across the room. Rick and Morty get out of the ship, freaking out over what they have done. Rick pins the blame on Morty as Morty runs around in guilt. Rick scoops up the remains of the family in a vial and gives it, along with the family portrait, to Morty. He uses the portal gun to open a portal to another dimension and sends Morty in, telling him to go to an address and get clones of the family. Morty enters the portal and follows the directions on the address he's given.
Meanwhile, Rick starts raiding the house, eating a donut and drinking some Duff Beer; albeit adding something far stronger to it after a sip. Morty goes to the address, and gives an alien working there the vial of Simpsons goo and picture. Rick goes into Homer and Marge's room, laden with loot from the house, and finds Marge's necklace and tries it on. The DNA from the vial is plugged into into a copying machine, filling up and it goes into a bottle which the alien injects into a large bison like alien creature. Ned Flanders walks into the house and comments on the big mess that's been made, in particular the space ship, and also noticing Rick and realizing that he's not Homer. Annoyed, Rick sighs and zaps him with the freeze ray and starts playing Lisa's saxophone again.
The animal's pushes eggs out of its snout, which Morty returns to the Simpson's dimension and gives to Rick. Rick dumps them all out on the couch and turns the thermostat to 110, the eggs hatching into The Simpsons. However, they all end up being deformed versions of them with Rick's skin and hair as well as his bad belching habits. Rick gives Morty a tip: never clean DNA vials with your own saliva. Taking his bag of stolen things, he and Morty get back into the cruiser, with Rick driving this time around and fly off, with them killing Flanders in the process by knocking his frozen body over and causing it to shatter. The mutated version of Bart then moans "No more guest animators man!", the gag ending.
