LOL... I'm gonna try that out, too! (Well, as soon as my friend returns my copy!)
Usually, I just hide in trashcans and listen to what people say. The Jocks have tendency to gather around one in the daytime.
I also like driving the moped/go-kart into the football field and running Jocks over. Sometimes, I'll just ride Jimmy's bike around the school and run over little kids/prefects. The prefects do an epic jump when they see you heading at them.
Ah, good times.
