...enemy deserve no mercy."

Johnny:

[Kreese and Johnny are arguing in the parking lot after the All-Valley Tournament]
Come on, that's not fair! I got Second place! John Kreese:
Second place? Second place is no place! You're off the team! Johnny:
That sucks! I did my best! John Kreese:
What? Johnny:
I said I did my best! John Kreese:
You're nothing! You lost! You're a loser! Johnny:
No, YOU'RE the loser, man! John Kreese:
Oh I'm the loser huh? [grabs trophy from Johnny and breaks it, sending pieces flying] John Kreese:
Now who's the loser? Johnny:
You know, you're really sick man! John Kreese:
[Kreese grabs and puts Johnny in choke hold; Bobby runs up and tries to stop it, but Kreese swats him away]
How does Second place feel now? Tommy:
Come on, he can't breathe! Bobby:
Sensei, please... you're hurting him! He's sorry, he really is, OK? Mr. Miyagi:
[walking up to Kreese]
Let him go. Tommy:
Yeah, Mr. Miyagi's right! Let him go! [Kreese backhands Tommy] Mr. Miyagi:
[louder and firmer]
I say, Let him go! John Kreese:
Beat it, slope, or YOU'RE next! [with a grunt, Miyagi forces Kreese to break his hold and free a gasping Johnny by grabbing his back and pushing him. Kreese tries to strike at Miyagi twice, injuring both hands in the process by slamming his fists through two car windows. Miyagi forces Kreese to his knees] Mr. Miyagi:
"Mercy is for the weak... when man confronts you, he is enemy... [Kreese is staring fearfully at Miyagi, remembering his own words] Mr. Miyagi:
...enemy deserve no mercy." [Miyagi growls and brings his fist to Kreese's nose, but honks it instead of delivering a fatal blow. Kreese collapses in humiliation as Miyagi smiles and winks at Daniel]
