Kung-Fu Chicken
A Kung-Fu master who talks about how great Kung-fu is, and how it is much better than any and all other martial arts, but, when you offer to do some full contact sparring with him, even with rules, and gear, and a neutral referee, he just CHICKENS OUT!
Jet Li says that Kung-Fu is the best, but, he refuses to fight Matt Hughes! What a Kung-Fu Chicken! MMA rules!
