fill his room with panthers, but make sure they're the black spotted kind which are endangered. then add some impalas, with heartbeat monitors that are linked to acid bombs. when the panthers go for the impalas and kill them, the bombs will detonate, turning the panthers into a fine mist which will stink to high heaven. when the RAs come show them photoshopped pictures of your roommate and benjamin netanyahu planning the whole thing and BAM, your roommate gets arrested for killing an endangered species, and 1990's israel loses US support, culminating in a pan-arab victory which strengthens anti-american sentiment abroad.
