Every martial art has potential if you spar and try to apply your techniques in a setting where the person is resisting! Although, I think it'd be funny for someone to make some kind of Cheapshot-do. The art of attacking someone who doesnt know you're going to attack them! Perform deadly wristlocks and all sorts of unrealistic moves. I'm sure you could do a double spin jumping kick to someone who was standing waiting for a bus... just attack them from behind!
