The Sundae Family couch gag is the ninth couch gag of Season 22.
The couch is an ice cream bowl. An arm releases five scoops of ice cream that resembles the Simpsons into the bowl, then tops the ice cream with chocolate syrup, whipped cream and a cherry. Santa's Little Helper (who's gigantic) comes in, sniffs it, and happily licks the sundae, while taking scoops of the ice cream away. After he finishes, he burps as he leaves the room.
