"Kitty Kitty Bang Bang" is an episode of The Itchy & Scratchy Show.
Itchy and Scratchy are at a bowling alley. Itchy jams Scratchy's tongue in the ball returner, then lights the fuse on a round bomb and bowls it into the pins. Scratchy sees the bomb coming back in the returner, screams, and desperately tries to saw his tongue in half to escape. But before he can do it, the bomb returns, lands on his tongue, and explodes, blowing him to bits. Itchy then sells Scratchy's remains (Cat Ligaments, 79¢/lb.; Cat Intestines, 59¢/lb.) to hungry dogs at the snack bar, who consume them with gusto.
