Hochstetter: You men are all assigned here. Until we catch those traitors, Stalag 13 will be under Gestapo control. No one in or out without my permission.
Klink: What about me?
Hochstetter: You may come and go as you please, Kommandant. Hopefully, you will go.
Hogan: You should lay off that liverwurst, Schultz, it's softening your brain!
(Attempting to distract the guard, points to the sky and cups his ear upward)
Newkirk: Hey, Schultzie?
Schultz: What is it?
Newkirk: Schultz, listen!
Schultz: I don't hear anything.
Newkirk: I know; it's been like that all day!
Klink: I assure you I shall give the Gestapo my complete cooperation, Major Hochstetter.
Hochstetter: Ja, even that will not discourage me.
(Carter has just screwed up)
Carter: How do you figure that?
Hogan: Easy. You just blew World War II.
