* HilariousInHindsight: Jokes about how "that is why this show will never be televised" after a scene in which it's implied someone's naked, etc... the show ''was'' eventually televised, albeit with puppets.
** Also, Count [[Series/{{Sherlock}} Jim Moriarty's]] name.
*** This was, of course, an intentional parody of the original James Moriarty's name, but to be fair, nobody had ever seriously called him Jim until ''Sherlock''.
* MemeticMutation: A pre-internet example - "Lurgi" remains a common British word for generic illness and is sometimes used by children instead of 'tag' in schoolyard games.
* OnceAcceptableTargets: There are jokes about singer and occasional guest cast member Ray Ellington being black that, while obviously made with his consent, tend to raise modern eyebrows - e.g. another character is blackened in a [[NonFatalExplosions Harmless Explosion]] and is promptly mistaken for Ellington. Even at the time, the show was criticized for being anti-Semitic with regards to minor Jewish characters/bystanders such as show business agent Lew [ironically, Sellers, who was half-Jewish, usually played those roles].
** And then there's Yakamoto in "Napoleon's Piano". "What's he do?" "Nothing, he's just here to lend colour to the scene."
** "How on earth shall we defeat him?" "I've found a chink in his armour!" "Those Chinese get everywhere."
