I went upstairs during a party once and for some reason decided to open the door that went to the third floor. There stood a guy taking a leak in the stairway. When I opened the door, he didn't stop, but grabbed a poster off the wall and held it over himself while continuing to pee. I laughed hysterically - what else is there to do? He finished peeing and stomped out of the house out into the cold and apparently walked home, leaving his brother, who had walked up behind me, to say "He's very sensitive."
