Take a baking sheet and line it with a sheet of wax paper. Piss into the pan, and stick it in the freezer. Once it's frozen, go to the victim's dorm room and slide it under their door while they're sleeping. By the time they wake up, they should have a nice, wet surprise on their carpet.

I'm not sure why you wouldn't just piss under their door, dump a bucket of piss under their door, etc. The whole freezing/sliding under the door thing seems like a lot of work for not much payoff, especially when you factor in the chance of them waking up before its thawed.
