A few years ago when I was still dorming, in my "substance free" dorm, I was drunk and I got off the elevator and dropped a huge 7-11 cup filled with beer right in front of the front desk. I just got the fuck out of there.
Or there was the time when we were throwing rocks at my next door neighbors house, which was vacant at the time. WE were trying to break the windows, but they were seemingly indestructable. The only thing we ended up breaking was this pvc water pipe which started a huge fountain of water. Then my the neighbor two houses down came over fuming. We told him we lived down the street and we were trying to get fruit out of the trees.
Then there's other things, like throwing couches and the like off of a 13 story building, or driving over trees in the mall parking lot
