|First Appearance||"Sweet Seymour Skinner's Baadasssss Song"|
|Voiced By||Dan Castellaneta|
Leopold is Superintendent Chalmers' assistant. He is a large, surly, snarling man. When Principal Skinner had to be temporarily replaced, Leopold stomped in, issued several threats, and terrified the children, making them think he was the replacement, and then suddenly politely introduced the actual substitute, Ned Flanders. The children then collectively sighed with relief. The gag was repeated when Marge Simpson became a substitute teacher when the teachers go on strike.
Behind the LaughterEdit
- He is one of the few characters on The Simpsons to have eyebrows.
- A similar gag was used in Mayored to the Mob when Leavelle starts berating his students, and makes it seem as though his students are going to fail his academy, he then suddenly tells them that they've graduated from his class.
