well i wanted to see what was the stupidest thing possible to do in class, and i'm sure you would like a laugh as well.
mine-i was in math class and was pushing a friend out the window, the teacher walked in......
(we were just kidding with the window pushing, no ppl where hurt, accept when i was hit by a snowball)
SO TELL ME YOUR STUPIDEST THING YOU HAVE DONE IN CLASS(sry for caps)
