The Simpson Biscuits couch gag is the third couch gag of Season 23.
Instead of the couch, in its place is a Christmas plate on a Christmas placemat along with a glass of milk. The Simpsons are gingerbread cookies, and they walk in and lay down together on the plate. A hand puts a "For Santa" notecard next to the plate. Gingerbread Homer looks at his left arm and eats it.
