Sammo Hung is the funniest martial artist actor in the history. He is known by acting in films like Fat Dragon (where he acts as a Bruce Lee fan that learned every move of The Dragon, and then showed people that being fat is not a synonym of being clumsy), and is a close friend of Jackie Chan.
His real name is "Kampo", but he's called "Sammo" by his mother because of an ancient chinese commediant called "Sammo" (=three hairs).
