Terry Silver: A man can't stand, he can't fight.
Daniel Larusso: I know you don't believe in fighting, but tournament karate isn't exactly fighting.
Mr. Kesuke Miyagi: Not exactly ping-pong, either.
Daniel LaRusso: Hey, I'm not going to fight. You can't make me fight!
Terry Silver: You don't have to. You can just stand there and let him kick your ass!
Terry Silver: He'll get up. He's too dumb not to!
Daniel Larusso: You know, this is the 80s, Mr. Miyagi. You can't be so damn passive.
Terry Silver: I owe you, man.
John Kreese: You don't owe me anything.

John Kreese: I don't know. I lost count.
Mr. Kesuke Miyagi: Inside you same place you karate come from.
Daniel Larusso: My karate comes from you.
Mr. Kesuke Miyagi: Ah. Only root karate come from Miyagi. Just like bonsai choose own way grow because root strong you choose own way do karate same reason.
Daniel Larusso: I do it your way.
Mr. Kesuke Miyagi: Hai. One day you do own way.

Mr. Kesuke Miyagi: If karate used defend honor, defend life, karate mean something. If karate used defend plastic metal trophy, karate no mean nothing.
Terry Silver: Look at this. Ten years ago, nuclear was the preferred waste. You could dump it anywhere! Now everybody's a detective. I'm lucky if I make one deal a year without being indicted.
