- William Potts: [after Rudolph Muller reams him out in German] Blimey! Hear what he's calling me? Said I got a face like a half-baked Wiener Schnitzel. Blimey, look at him. He's no oil painting, is he?
- Rector: You are late, Herr Muller. Berlin informed me that you were reporting for duty yesterday.
- William Potts: Well, yes, I'm sorry, Herr Rector, but uh, you see, the plane, er, uh uh, the train, through Spain, stopped again and again and again.

- Prof. Hoffman: I'm sure the British people are longing for the day when our beloved Führer will set foot in Britain to liberate them.

- William Potts: Uh, the warmest he's ever had in his life.
- Prof. Hoffman: Splendid, splendid!
