I did it once. Wasn't as long and drawn out as the way most of them seem to go. I enjoyed it. Unfortunately their was a stupid cunt that wouldn't listen no matter how many times you proved everything she said to be absolutely retarded. the teacher had shown some movie about how some guy was stubborn and then changed everyones minds or something and saved the day. I think she was trying to be a hero.
But seriously ask some people at your school who have done it. It depends on who's running shit and who's involved. Could be kind of fun, could be a huge buzz kill
