cut my thumb right at the join clean to the bone. i was lucky and it was only the side of the thumb joint. I think the worst i ever did was a dare to put my head in the locker.. i won but it took 30 mintues to get the door off it hinges so i coule have it removed from my head (wet thought the vented section i still got the scar onthe chin to prove it . dang metal didn't bend enough to allow self removal lol.
