Preston Mudd

Preston Mudd was a kid and minor character that only appeared in the first book. He was a very good athlete and even made "Athlete of the Month" but on the plague, his name was put as P. Mudd. Some boys found out it sounded like, Pee Mud and they start making fun of Preston for it. He hasn't been mentioned since. This caused Greg to believe he shouldn't do the best in gym.

Trivia

 * If you look closely in the movie, you can see Preston's plague in the hallways, though, he himself doesn't appear in the movie.
