lol I indirectly used to do that a lot. In a boring 1 hour class, where the teacher only solved about six problems, I'd go ahead and solve as many as I could, generally twenty or so. That way I'd always have done anything the teacher might ask for as homework =p
Algebra- I draw random comics of carnovious numbers destroying human kind and how a psycotic mall cop who thinks the government is trying to kill him it fighting them in attempts to save his daughter he doesn't have, because he's never donated to a sperm bank, and he's a virgin.
Computer Applications: Doing what I'm doing now, I'm on MAL..I do nothing in this class except this ((and I'm serious, no work)) and I'm passing.
Art- I draw what I'm not supposed to, procratinate untill the last 5min of class, quickly sketch what I'm supposed to and turn it in and get either a C or a B on it.
World Geography- Easy class, get my work done in about 20minutes then I play my brotehrs game boy that he has no idea that I have...he thought he lost it.
Japanese- This class is never boring
Web Mastering- I'm on the MAL forums
English- I draw comics on how Letters and Numbers join forces and try to kill man-kind, and how the psycotic mall cop joins with a 14 year old mage that utterly fails at his magic and can barely use Arcane....O.o
Biology- This class tends not to be boring because I make it fun
I actually did masterbate in class one time. It was one of the last days of school and we were watching a movie with the lights off, I was so bored that I just stuck my hand down my pants and rubbed one out.
I slacked off way too much in school. I almost never payed any attention to what the teachers were saying half of the time. I would either read a book, sleep, stare out a window/into space... or just draw random things on paper.
