Burkhalter: Is it possible I have been underestimating you all these years, Klink? No, it is not possible.
Klink: Sir, there is no reason for you to worry about security!

Kinchloe: Lay him out? The problem's gonna be keeping him on his feet.
Klink: Hello, Colonel Klink speaking, Heil Hitler… Oh, General Burkhalter, how very nice to hear from you… What's that, sir? Yes, sir, "shut up and listen," yes sir.
