Whew* got thru fine, although...
Two of my teachers desk were turned around. Both of them thought the stuff ON it had been turned backwards, so they turned the stuff around. The when they sat down they banged their knees and had to turn the desk around then the stuff around.
Also, in one of the bathrooms, someone took a 20 year old chunk of spam, and put it in one of the toilets(stall) in three of the sinks, in one of the other toilets, and on the wall. Smelled terrible. That and someone pissed, then took a crap inside the toilet. There was ketchup in one too...
Heres a good joke to play on someone...during the night, secure the handle on the kitchen sinks hose so that its on(rubber band, etc). then point the hose at the place where someone would stand. As soon as they turn the faucet on, bam, theyre soaked!
