Do people not know why Liu Kang does his turkey noise? Its not for the jokes. Its something serious in matrial arts. I thought was for jokes to till I researched about it when I was kurious about it. I am pretty sure Liu Kang does it the same reason Bruce Lee does.
Here you go:
"Almost every martial art has its characteristic sound, expelled when the fighter attacks or defends. In Japan, Karate and Kendo use the "kiai" and the most ancient kung fu styles along with some korean styles use a kind of "heyp". Producing this sounds while attacking force the fighter's body to contract muscles and expel air from the lungs. By doing so, you're not only increasing the strength of the strikes and defense movements, but also preparing your belly and rib muscles to absorb a possible counter attack.
Great masters change the sounds produced during the fight and Bruce Lee had reached those sounds as he built his personal fighting style. Of course, the sounds we hear in the movies have an artistic effect, but in real life fights, Bruce would probably sound something like that.
Jet Kune Do works with fast and piercing attacks, the penetrating "wa" made by Bruce Lee was a perfect match to those moves, helping the mind to go into the correct state to the fight and confusing the opponent."
Its not for jokes guys.
It makes me want to kry
