Have a good room mate story to tell?

In my freshman year of college, I was rooming with a friend of a friend who I didn't know very well. Over the course of six months, he would put up very strange decorations (I didn't object, it was just hilarious to find without any warning). We didn't talk at all because we were never in the apartment at the same time. First were the posters of female celebrities, then the posters of porn stars. Then dirty limericks on the fridge and oddly enough, philosophical quotes in the bathroom. Finally, I found in the TV room. They sing and are called Jiggly Jugs! Share your stories!
