Sitting in my room, relaxin all cool, browsing the internets when a giant ass spider started making trouble in my dorm room.
Roommate, brushing his teeth makes an alarmed "waaAaah!" sound with a toothbrush in his mouth. I come out to see what the problem was only to be pointed at the sink... Four legs wrapped around the top of the sink stopper. Enormous spider legs. I look underneath to find the largest spider I've seen in years.
My other roommate crawls out of the woodworks to see what was going on and thus began the stalemate. Three grown men standing around in indecision as to how to deal with the monster that had appeared in their midst without causing it to go back down the drain. (They come back, they always come back.)
Roommate 3 eventually puts on his gwar face, wraps a hand-towel around his fist and punches it to death. It survived the initial strike, merely stunned.
In the end, the spider was defeated, its blood soaked through the towel. We placed his body outside our front door as a warning to future trespassers.
