Cpt. Anderson: Well, Owens?
Pvt. Owens: I didn't mean to bang the door, sir!
Cpt. Anderson: Then why did you do it? You always do things you didn't mean to do, Owens?
Pvt. Owens: Sergeant Moore, sir. He said on the double, and-
Cpt. Anderson: But he didn't tell you to bang my door, did he?
Pvt. Owens: No, sir.
Cpt. Anderson: Did you bang my door just to irritate me?
Pvt. Owens: No, sir.
Cpt. Anderson: Now, you were supposed to knock, weren't you?
Pvt. Owens: Yes, sir.
Cpt. Anderson: Then get outside and knock!
Pvt. Owens: Aye-aye, sir!
[Owens goes outside and shuts the door. He knocks three times on the door frame.]
Cpt. Anderson: I can't hear you! [Owens hits the frame three times, harder.] I still can't hear you! [Owens hits the door three times, very loudly.] Get in here!
Pvt. Owens: Sir, Private Owens reporting as ordered, sir!
Cpt. Anderson: You know what this is, Private Owens?
Pvt. Owens: No, sir.
Cpt. Anderson: This is a general discharge. Your discharge. It's all filled out. The only thing stopping it from going through is my signature. Do I sign it?
Pvt. Owens: Sir, I-
Cpt. Anderson: If I sign this, Owens, it'll be the end of this island for you. No more training, no more Sergeant Moore. You'll be a playboy again. You want that very badly, don't you? Yes, all I have to do is sign it. You're such a baby, you'll probably break down and cry if I don't sign it. Do I sign it, yes or no?
Pvt. Owens: Yes, sir.
Cpt. Anderson: You're wrong, Owens! I don't sign it. [Tears up the discharge] Not for you, never for you. It's your country, Owens. That's what country it is.
