I blame Jeremy Beadle and Harry Hill now he's taken over. People always laugh at a stack, only have to worry about the ones who keep laughing if it turns out to be a proper injury.
Could be worse I fell down a flight of concrete stairs. 2 guys at the bottom asked if was ok to which I replied I think so, at which point they shot me because I was on the opposite team. Think I was laughing more than they were.
