I remember as a kid at the Royal Show seeing a show before the holden stunt drivers....

clowns (the type with red noses, big shoes and face paint) in shortened minis, with large external circular roll cages. they would drive, hit the skids which were biased to the front creating a massive endo but due to the roll cage the car would somersault over onto it's wheels again. pretty easy in a shorty i would imagine.
