There was a period last year where I awoke to find piss either in my wastebin, in a drawer full of t shirts (And quite a high one, I have no idea how I positioned myself) or all over my bass rig. It's weird, cos the nights it happened I recall leaving the club, going to bed etc and so attribute it to alcohol assisted sleepwalking.
I'm especially proud of giving a pin badge that said 'FUCK YOU YOU FUCKING FUCK' to Snooker legend John Virgo at about 4am in a hotel bar as well. Course, he was a lot more wasted than we were. He read the badge, absolutely pissed himself laughing, I gave it him, he muttered something about knowing the guy from Jethro Tull and we went to get a taxi. Kickass.
