The little cylindrical structure, medical station on the bottom level of Turf is one of the glitchiest places in Halo 2. Have one person stand inside the structure, and another person assassinate the first person while staying inside the medical station. If you do this right, the dead body will flop around and slap himself in the face with his arm. To make the person slap their self, they have to be lying on their side. If they are on their back, the arms will only constantly twitch.
