Oh, the fun we've had in computer classes in school... Out high school was math-oriented, so there's a bunch of 14 year olds who spend 6 hours a week proving theorems and lemmas – and learning a local dialect of Lisp made by our school stuff. Obviously, there were a long of shenanigans, trojans, and DOS attacks, but the best part was when my classmate got so annoyed by his PC restarting for the third time just as he logged in and opened his IDE third time in a row, he physically attacked a classmate who he thought was responsible. (He wasn't, it was me, from another classroom). After that, our whole class was downgraded to DOS as collective punishment.
