P.U.

P. U. is an episode of The Itchy & Scratchy Show. Bart and Lisa watch it in the family's station wagon.

Plot
Scratchy gets married, to enthusiastic applause from the cats attending the wedding. Scratchy and his bride buy a fixer-upper home and settle into a contented married life of working on their house, picnicking and cloud-watching on a nearby hill, and growing old together in the house after the renovations are finished.

Years later, Old Scratchy and Mrs. Scratchy re-visit their old picnic spot on the hill. Itchy suddenly appears with a machine gun, opens fire and riddles the two of them with bullets, killing them on the spot. Itchy later visits their graves and blows them up with dynamite. The ghosts of Scratchy and Mrs. Scratchy float up out of the crater, and Itchy uses a canister vacuum cleaner to suck them out of the air. Itchy removes the bag from the vacuum's canister, and the forms of the ghosts can be seen as lumps moving around in the bag. Itchy then sets the bag on fire, and the ghosts scream as the bag burns up.
