competition: Stupid Ways You Had ACCIDENTALLY Hurt Yourself!!

FIRST DAY OF SCHOOL!
okay so my forth period class runs in and my friend is telling me to sit next to her. so, the idiot i am, i try to take a short cut, and accidentally step on the back of another desk thinking it's the floor and trip, hit my head on another kids desk (sharp edge) and bang my head against the metal bar of the same desk with the sharp edge. i felt like a ping pong ball!
