We can't wait to see the couch gag for this episode. Our greatest hope is that it's an amalgamation of the two shows. Heck, they could do a completely special opening sequence for this episode - have Marge driving the Planet Express ship instead of the car at the beginning. Have Hypno Toad show up at the end. Find fry sleeping on the couch when they finally make it to the living room. The Simpsons have had a lot of good couch gags of late (Game of Thrones for example). This one has lots of possibilities.
