Well... hopefully the guy either has some sort of insurance that will cover that, or really rich and really understanding parents!
Something similar happened when I was at school. They always tell you NOT to hang anything from the sprinklers. Well, guess what, this guy decided to hang a sweater up there to dry. I heard that he realized it right after he hung it up there and went to take it down, but of course by then it was too late. It ended up flooding 3 floors of the dormitory, and his parents' insurance had to pay for the damage, which I'm sure totaled more than $50,000!
