"O Solo Meow" is an episode of The Itchy & Scratchy Show.
Scratchy is at an Italian restaurant. Waiter Itchy serves Scratchy a plate of spaghetti with a bomb in it. Scratchy eats the spaghetti, not noticing the bomb until he's just about to swallow the fuse. Panicking, Scratchy tries to run out of the restaurant through a low doorway, hits his head on the door frame, and is beheaded. The rest of his body runs outside and explodes. A dog waiter carrying a tray full of dishes trips over Scratchy's head and falls down, scattering dishes everywhere. Itchy laughs at the sight.
