First Appearance: "There's No Disgrace Like Home", Season 1. A parody of Tom from Tom & Jerry, Scratchy is the brunt of Itchy's psychotic schemes, traps, and disembowelments.

Funniest Moment: It's hard to pick one, so here's a rarely-seen clip from a Sky1 commercial celebrating 20 years of The Simpsons.
