The Karate Kid (1984)

Daniel: You're the best friend I've ever had.
Miyagi: You... Pretty okay, too.

Miyagi: Wax on... Wax off. Wax on... Wax off.

Daniel: Hey, where did these old cars come from?
Miyagi: Detroit.

Lucille Larusso: Look at those palm trees. Damn! You know what that means?
Daniel: Yeah. Watch out for falling coconuts.

Daniel: Why didn't you tell me?
Miyagi: Tell what?
Daniel: That you knew karate.
Miyagi: You not ask.
Daniel: Well, where'd you learn it?
Miyagi: Father.
Daniel: But I thought he was a fisherman.
Miyagi: In Okinawa, all Miyagi know two things: fish and karate.

Miyagi: We make sacred pact. I promise teach karate to you, you promise learn. I say, you do, no questions.

[Miyagi karate-chops the tops off three beer bottles.]
Daniel: How did you do that? How did you do that?
Miyagi: Don't know. First time.

Daniel: When do I learn how to punch?
Miyagi: Better learn balance. Balance is key. Balance good, karate good. Everything good. Balance bad, better pack up, go home. Understand?

Daniel: This school sucks, man. Sucks.

Daniel: Wouldn't a fly swatter be easier?
Miyagi: Man who catch fly with chopstick accomplish anything.
Daniel: Ever catch one?
Miyagi: Not yet.
