Just a little bit of self defense, and having watched with friends some martial arts movies, of course. I think that the funniest is Jacky Chan (no need to say that Bruce Lee was outstanding, of course), and I did not mention the Kurosawa's famous "works", like the "Seven Samourais", "Kagemusha", etc.
And I have also read a lot about them and the different disciplines - well, after all, I was and still am a bookworm - lol.
