I didn't do much stupid things when I was drunk. Worst would be drinking too many different things and ending up throwing up.
Friends though
Drinking a bottle of some liquor before the party together with beer. Drinking beer at the party. Throwing up over his smoking and getting his father called out of bed. And now the best thing, leaving the party (he had to go through all of the building which happened to be a Hilton hotel) with someone holding a bucket under his nose and 2 supporting him while he turned completely green and could barely walk.
Another one put a bicycle on the roof of our hockey club's building. He couldn't put his empty beer bottle back in a crate and his eyes were completely red and then he found it was a good idea to follow the bicycle. So he tried climbing up the building but fell off from like 2-3 meter on his back.
Having your hair completely shaven off next morning. Now I have to be careful saturday
