Rectum Rocket

Its a simple idea, you get a footlong piece of piping insert one end into the offending orifice and light the other end. Away you go with the rectum rocket which claims to be powered by a can of beans and 4 chillies. Nah, really they just got a rocket engine and strapped it to a bike, filled it up with roof tar so it would burn good and set it free. Now it roams the neighbourhood and is uncontrollable by anything but a small gorilla armed with a baseball bat.
