There appears only one logical and rational decision. Go to your nearest guns & ammo shop and buy a 12 gauge and a box of shells. Go to the local crackhouse and pick up a nice hit of heroin. Smoke a joint, go into a room with no windows or any means of escape. Pump that cheecky bastard full of Heroin and release him. Next load the 12-gauger and fire away until you send the possessed bastard to the fiery underworld. Then release an evil ghoulish laugh and buy yourself a hamster.
