Do what Bruce lee does, Learn to fight without fighting. Like in one of his movies where some caucasian was showing off his speed and challanged Bruce lee on a boat. Bruce let him on the small boat first and then untied the rope so he's off the boat and can't get anyone. Which I would say is very funny. Now if your not on a boat. Try saying lets take it outside, open the door for them and lock it after they leave.
Well I suggest only doing this when you do know martial arts. I never really had an experiense where I have to fight cause someone thought I do martial arts.
Everyone lets all gather around and sing this song "Kung Fu Fighting" Lyric: http://www.lyricsondemand.com/onehitwonders/kungfufightinglyrics.html
No way man! Those movies are awesome! Some are so bad... that... they're awesome! lol. Like... stupid funny, but they have those Chinese Vampire movies... LOVE those! And they use to do a lot of kung fu movies. The ones now aren't as good. They have all the, guns and stuff mixed in. Although Crouching Tiger was a good one... meh there are only a couple new ones that are good. But the old kung fu movies are still the best. But... Crouching Tiger is awesome.... lol.
