Funniest festival unfortunate I've seen was at Reading. There's a bridge going over one of the rivers in the campsite and people had lined up, 2 lines facing each other, before the bridge with their arms meeting at the top like a tunnel. The people at the front are saying 'Don't go through the tunnel!' but there's always one kid who goes through anyway with a fat grin on his chevy, shouting to his mates and feeling famous. Jokes on him though when the people towards the end of the tunnel move to be just in front of the river and the tunnel forces him out the end straight into it.
