JJL- you're Scottish- doesn't that mean you're never sober?
-and did you mean your pants in the American or British meaning?
I think the stupidest thing I did when drunk was have an argument in the middle of a pub with a girl I was seeing infront of all her workmates. I walked out, and then thinking it would look cool in a 'movie-type-way', I stormed back in expecting to make a grand statement that would make me look great. Instead she ignored me and I looked like a right tit as two burley blokes man-handled me out of the pub.
I also tried to jump a pavement in a graveyard on my bike whilst doing about 100 mph downhill, didn't figure on the fence that came flying towards me and promtly slammed into it trashing my bike and bashing my front teeth in.
