Things got a little out of hand, the van wouldn't move, and a couple dudes ended up trying to defecate on the hood of the vehicle. While they were unsuccessful in their attempt to leave a mark, they did damage one of the fans under the hood. Word got around and the university came down on them. One of the guys told us that charges might be pressed so he had to lawyer up. IIRC, they had to delay mission stuff as well.
I also had a friend who was intent on catching a duck and putting it in our FHE sisters' dorm. A fair number of us thought it might be amusing so we went down to the duck pond and chased ducks around both in and out of the pond for a couple hours at about 1:00 in the morning. Thankfully we were unsuccessful. I don't think it would have ended well if we actually caught one.
