The shower is probably the most vulnerable place in an entire dorm room. You need to be naked to take one, or else things could get weird. And if you don't take one, you're going to be pretty socially ostracized. If you've drawn the attention of a group of pranksters, you have to expect something horrible might happen to you the next time you rinse off. For this poor dude, it was four giant buckets of salted ice water over his dome.
