Martin Prince is one of Bart's classmates on The Simpsons and is a genius. Unfortunately, his nerdy characteristics make him a target for bullies. He and Bart, although rivals at points, seem to prove to be friends and have even gone on an epic road trip together.
Principal Skinner: Whoever did this is in very deep trouble.
Martin: And a sloppy speller too. The preferred spelling of "wiener" is 'W-I-E-N-E-R', although 'E-I' is an acceptable ethnic variant.
Martin: Bart, I hope you won't bear some sort of simpleminded grudge against me. I was merely trying to fend off the desecration of the school building.
Bart: Eat my shorts.
