The Lethal Opening Sequence couch gag is the third couch gag of Season 10.
The family never makes it to the couch; Bart falls off his skateboard, breaking his neck. Lisa gets catapulted into the garage roof, and Homer gets run down by Marge as she drives into the garage. Meanwhile, in the living room Freddy Krueger (of the A Nightmare on Elm Street movies) and Jason Voorhees (of the Friday the 13th movies) sit on the couch, wondering where the family is.
