Martin: Klink must be an idiot.
Hogan: Oh, he has his good points if you look for 'em. 'Course, that could take a lifetime.
Hogan: At ease, Captain. We try to maintain an informal atmosphere here at the Enchanted Castle.
Martin: Thank you, sir.
Hogan: Seems to go with the beautiful surroundings.
Schultz: A very nice guy.
Klink: Shut up!
Carter: I've got my charges all set, sir.
Hogan: Forget it. My first responsibility is the protection of this unit.
Carter: The Colonel's right. In a way, we are his family.
Hogan: Oh, I'm in a lot of trouble!
Hochstetter: (pointing at Schultz) He is not adding anything to this meeting.
Klink: Except weight.
Martin: Did you say "emergency tunnel?"
Hogan: Yeah, it's part of our system: we have an emergency tunnel (a tunnel out of camp,) a tunnel to the cooler, and a tunnel to Klink's quarters.
Martin: (laughs) That's fantastic!
Hogan: Someday we'll steal a train; we've got ourselves a subway.
Klink: Major Hochstetter, are you suggesting that Stalag 13 has any relationship to this sabotage, huh?
Hochstetter: At last a little daylight filters through.
Schultz: Uh, shall I raise the blinds?
Hogan: We earned our money for tonight.
Newkirk: Not just tonight; this is the second big job this week.
Carter: We've been busy as beavers. We oughtta get something extra for this job.
Hogan: Wait 'til Christmas: I'll get you a nice set of Kraut trains to blow up.
