Joe Clark:[Clark's roof-top pep-talk to Thomas Sams] Now let me tell you something: The trouble with being a teenager is you don't know nothing. The problem with teenagers is you think you're smarter than people who already been down the road you're traveling. You know what I'm tryin' to say to you, boy? DO YOU?
Thomas Sams: Yes, sir.
Joe Clark: Did you tell your father I threw out of school?
[Sams, with his head down, doesn't answer]
Joe Clark: [picks Sams' head up; yells] Look at me DAMNIT!
Thomas Sams: [sobs] No, sir.
Joe Clark: Why not? No guts, huh? Afraid of what he's gonna say to you, aren't ya?
Thomas Sams: My father doesn't live with us anymore, sir.
Joe Clark: Oh, is that you're doing right now? Going around, feeling sorry for yourself, boy? Huh? Go on. Get outta here! You're wasting my time!
Thomas Sams: [crying] Please let me back in, sir. I have to get back to school. I can't go home and tell my mama I got kick out of school.
Joe Clark: Now why should I let you back into my school, Sams?
Thomas Sams: 'Cause I'm gonna do better, sir.
Joe Clark: How?
Thomas Sams: By doin' my work.
Joe Clark: What else?
Thomas Sams: And stayin' out of trouble.
Joe Clark: What have you been thinking about all this time? Why should I believe you now?
Thomas Sams: 'Cause I've changed my ways.
Joe Clark: I don't believe you, Sams. I don't think you changed a thing. Go on, jump!
Thomas Sams: [sobs] No, I don't wanna jump!
Joe Clark: Yes, you do! You smoke crack, don't ya? You smoke crack, don't ya? LOOK AT ME, BOY! Don't you smoke crack?
Thomas Sams: Y-yes, sir.
Joe Clark: You know what that does to you? Huh?
Thomas Sams: No, sir.
Joe Clark: [taps Sams' head with his finger] It kill your brain cells, son. It kill your brain cells! Now when you're destroying your brain cells, your doing the same thing as killing yourself. You just doing it slower! Now, I say, if wanna kill yourself, don't fuck around with it. Go on and do it expeditiously! Now go on and jump! JUMP!
