"From Here to Infirmity" is an old black-and-white commercial starring Itchy & Scratchy.
Itchy and Scratchy are making out and moaning on the beach when Itchy drags a shark and Scratchy kisses it instead. The shark tears him apart and the director of the show stops it for the commercials. Itchy starts smoking a cigarette and a mutilated Scratchy soon joins him. The episode ends with Itchy, Scratchy and the director coughing up tobacco.
