Revealing mistake: When Mr. Lucas gives Mrs. Slocombe the radio mike, it slips down her dress out of reach; Mr. Harman says "It can't have gone down all that far," and he's right: The short cord of the mike is visible sticking out of the dress for quite some time until Mrs. Slocombe herself pushes the mike down (in the appearance of trying to fish it out).

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.
