"Let Them Eat Scratchy" is an episode of The Itchy & Scratchy Show.
Plot
In a swashbuckling setting, a rapier-wielding Scratchy chases Itchy through a room. They get to a closed floor-length curtain, and Itchy goes under the curtain. Scratchy pokes his head through the curtain to look for Itchy, and the curtain opens to reveal that Scratchy has stuck his head into a guillotine. The blade falls, beheading Scratchy and sending his head rolling into the room. When Scratchy's head comes to rest, Itchy jams a lit stick of dynamite into his mouth. The dynamite explodes, destroying all the flesh so that all that remains of Scratchy's head is his skull.
