During our stay together, my roomie:

He brought his motorcycle into our common room because he was "afraid it would be stolen." This was fine, but then he started it and let it idle for 15 minutes without opening any windows, causing all of our stuff to smell like motor exhaust.

After his girlfriend left him, he went berserk in his private bathroom with a sledgehammer or a geologist's hammer and smashed all of his bathroom fixtures. I'm not sure of this but I believe that just before she left him she fucked some guy with pubic lice in my bed during a party.

His toilet was inoperative at this point, so he used mine for a time, until I refused him access. Later I would find out that he shat in garbage bags and kept them in the common room closet for weeks. More on this later.
