oh sooooo many! but one that springs to mind...
went out one night and had far to many tequilas, later on walking past a car that was playing drum and base music VERY loud (the car was vibrating

) so i put my bum on it and started sayin ooooo have a go of that to my mates, they were all laffin, then the car drove of and i ended up on my back in the road with my legs up in the air! i lay there for about 5 minutes, think i might have fell asleep for a little while
Very bruised back and ribs the next day!
