‘Rick & Morty’ invade ‘The Simpsons’ couch gag

“The Simpsons” has had fun in recent years turning over its couch gag to guest animators, and this weekend, it's the turn of Justin Roiland and Dan Harmon, who bring in the heroes of their great Adult Swim comedy “Rick and Morty” to stop by 742 Evergreen Terrace. If you can't wait til Sunday – and/or are looking for some good “Simpsons”-related news in the wake of this morning's Harry Shearer developments – here it is. And if you've never seen “Rick and Morty” before, prepare to be very confused and possibly horrified.
