Seems like whatever fraternity ($1.65?) that was in charge of it had a dumbass stick his face in it when it went off. It was kind of cartoonish when it happened -- smoke coming from his blackened head as he fell to the ground. He ended up getting up and walking to the ambulance on his own accord. It was shortly after this incident that the cannon disappeared. Not sure if the events are related -- I always assumed liability premiums went up too high or the kids parents sued or something but never really heard the true story from anyone.
