The FOX couch gag is the twelfth gag from Season 5.
The Simpsons sit on the couch just as a translucent FOX station identification logo appears in the lower right hand corner of the screen. Homer sees it, gets up from the couch, peels it off, and stomps on it (with the family joining him in stomping it) before returning to the couch.
