Rick and Morty will drop in on The Simpsons for the long-running animated hit's season finale, making a cameo during its iconic opening. The pair invade the Springfield home of Homer, Marge, Bart, Lisa and Maggie this Sunday at 8 p.m. ET.

Executive producer Matt Groening comments on the mashup, saying, “This couch gag plays like a full-fledged mini-episode. It's going to be a real treat for fans of The Simpsons, fans of Rick and Morty, and fans of animated belching.”

Check out the opener below and be sure to tune into Adult Swim this summer for a new season of Rick and Morty.
