The Simpsons: 10 Best Couch Gags
3. Rick And Morty Crossover
First Appearance: "Mathlete's Feat" (22x26)
Rick and Morty has become one of the most popular and brilliant animated series in recent memory, so it was only a matter of time before the pair crossed over into the Simpsons universe.
The gag seemingly feels normal until out of nowhere Rick and Morty crash their ship into the Simpsons, killing them all. Rick sends Morty with a picture of the Simpsons to another dimension in order to restore them, while Rick keeps watch of the house. This includes stealing precious items from the Simpson house and freezing Ned Flanders. Morty returns where it is revealed that Rick cleaned the test tubes with his own spit, resulting in the family becoming grotesque versions of themselves merged with Rick's DNA.
This gag works perfectly, with the resulting crossover being beloved by fans of both series. It captures the essence of Rick and Morty perfectly, while featuring a multitude of references from Groening's other series Futurama.
