One I mentioned a while ago was pissing on a church... the act itself wasn't TOO bad but given the context, house of God etc probably wasn't the wisest choice for a toilet. I didn't realize it was a church until some woman started yelling at me over it.
The first time I blacked out I threw up all over the place inside my friends shed, then knocked over the giant cauldron campfire and almost burnt down his house

I got absolutely slaughtered on New Years about 6 years ago, I don't know what happened but no one would talk to me for 5 days afterwards.
Talked my friend into sleeping with a fat, ugly girl on her period because it'd be "funny"

Woke up in a phone box somewhere in England, the guy who found me called me Superman and basically told me to fuck off lol.
Dozens of ill advised phone calls and text messages.
