I havent done much but I 've seen my mates do some stupid things
one of them fell in grass and got a huge piece of glass stuck in his kneecap
one was opening a bag of salad at work with the knife and hit herself in the face with it
Oh yeh and i remember at crucial crew when i was about 11 (does anyone remember crucial crew?) there was a pole affixed to a wall that the army people had set up and it fell on my head as i was walking past. i got to see a real field medic
plus i fell over some boxes at work just the other day and im covered in bruises. It hurt at the time but makes me laugh now!
