German Week - S3-E6
Miss Brahms: I think Mr. Rumbold should dress up as something.
Mrs. Slocombe: Yes. Wasn't Frankenstein a German?
Miss Brahms: That's right. With his nuts in his neck. [Makes twisting motions with her fingers near her neck.] Like that.
Mr. Rumbold: I wouldn't be able to take part, of course, in case I was summoned to a board meeting. But I see no reason why Captain Peacock shouldn't participate.
Captain Peacock: I can think of lots of reason why I shouldn't participate. Somebody has to have authority over the floor and these clothes that I wear symbolize that authority.
Mr Lucas: Why don't you dress up as Hitler?
Trivia: Frank Thornton, Mollie Sugden, John Inman, Wendy Richard and Nicholas Smith are the only actors to appear in all 69 episodes of the show.
Question: Captain Peacock explained the real reason why he and Miss Hazelwood were late for work but, why did they both decide to hide the truth and make up a story as to why they were late? Why not just come right out and admit it? If they had, it would have been excusable.
