OK, legally, i think you're expected to give your roommate 30 days notice... Don't worry - there's a cool way to get around this.. First, you need to get someone that doesn't really have a lot of familiar connections - a homeless person, prostitute, hobo (not homo, you homophobic anantechers!), etc. When I say "get" I mean by any means necessary- there are many great,easily obtainable chemicals that can knock a grown man out for a good amount of time.. Then, get a nice, sharp, preferably steel cutting instrument and proceed to vivisect this individual... Save their organs in a cool, dry place- I picked up a "Foodsaver" vacuum sealer - keeps everything very fresh.. Now you may want to use all of these organs at once- DON'T! First, place one small body part in a spot that's clearly visible to your roommate.. When he/she asks what that is just refer to it as "lunch." Then, slowly, litter the room more liberaly with the body parts.. A heart in the medicine cabinet, a spleen in the bread box.. Eventually, lead up to severed reproductive organs on or in his/her bed.. Eventually, your roommate should leave on his or her own, without the need of an uncomfortable confrontation...
