What happens when alcoholic mad scientist Rick and his grandson/sidekick Morty invade The Simpsons season finale? Well, first they manage to kill the whole family in the couch gag, meaning that the pair then have to scramble to put the whole lot of them back together.

This is the couch gag for the May 17th season finale, which will air at 8pm on Fox. The characters from Dan Harmon and Justin Roiland’s Adult Swim show Rick and Morty. Even the press release is announcing the couch gag crossover is pretty darn amusing:

“This couch gag plays like a full-fledged mini-episode,” said The Simpsons creator and executive producer Matt Groening. “It’s going to be a real treat for fans of The Simpsons, fans of Rick and Morty, and fans of animated belching.”

“We are honored and blown away to be a part of The Simpsons,” said Rick and Morty co-creator and executive producer Justin Roiland. “If I could go back in time and tell myself that this would happen, I’d be like ‘No way, Jose!’ I simply can’t believe it. I think we might all be living in some kind of massive computer simulation to be honest. Look up simulation theory. That would explain how this happened.”

It’s canon now: Rick’s spit has invaded the Simpsons’ universe. And we’ll get to see more of these two and their scifi shenanigans on July 26th on Adult Swim.
