Sideshow Bob couch gag

The Sideshow Bob couch gag is the eleventh couch gag of Season 16.

Plot
The Simpson family enters the living room and sit on the couch as usual. "Homer" then pulls off his face (which is a face mask), revealing to be Sideshow Bob, much to Bart's horror. Bob pulls out a knife and chases Bart around and out of the living room as Marge, Lisa and Maggie hug each other and watch in worry.
