My roommate junior year of college ratted me out to the cops for buying him liquor. I turned 21 a month or two before him, he got busted with a pint of vodka and ratted me out. I was sooooo naive back then, I told the cops the truth. Honesty being the best policy, and all. Ended up spending two days in county in a "scared straight" type situation. The town surrounding the college was small, and afraid of turning into a party town, so they were fond of cracking down on alcohol offenses. It didn't stay on my record, or anything. All it was an expensive lesson in not being such a trusting, naive little dope about things.

He was a shit roommate all around. He was a slob who left bowls of half-eaten chili everywhere for weeks. He had a bootleg VHS tape of THE PHANTOM MENACE which he watched all the time. He was fond of analyzing Darth Maul's fight scenes, and sharing these deep thoughts with whoever happened to be around. He's generally the reason why I avoided science fiction for a decade, which I hate him for most of all.

I got some petty vengeance at the end of the year, tho. He had promised to pay for my court costs as an apology, but didn't, of course. So, I swiped his text books at the end of finals week, and sold them before he knew they were gone. It didn't come close to balancing the scales, but it made me feel better about it.

Probably more "horrific" roommate stories, but that's the worst one I've got.
