Gary Chalmers, aka Superintent Chalmers, aka Super Nintendo Chalmers by Ralph Wiggum, is Principal Skinner's boss on The Simpsons. Chalmers is definitely one of the most normal characters on the show and despises the incompetence all around him.
Ralph: What's a battle?
Principal Skinner: Hahahaha, lets go.
Superintendent Chalmers: Did that boy say what's a battle?
Principal Skinner: No he said What's that rattle, it's about the heating duct.
Superintendent Chalmers: Hmm, it sounded like battle.
Principal Skinner: I've had a cold, so--
Superintendent Chalmers: Oh so you hear r's as b's?
Principal Skinner: May I interest you in a jello brick, sir? There's a grape in the center.
Superintendent Chalmers: Well, I'm not made of stone.
