Quote from Barry in The Kara-te Kid
Coach Mellor: As you know, it is strictly against school policy to allow students to fight on school property. Adam: Oh, thank God. Coach Mellor: Which is why I'm allowing your brother here to start an official after-school karate club. Adam: What? Barry: Look, I already signed you up. Adam: I thought you were going to save me. Barry: I am, by letting the other Adam Goldberg kick your ass in a loving, controlled, school-sanctioned environment monitored by our most lenient teacher.
