Trivia / I'm Sorry I Haven't a Clue

  • Actor Allusion:
    • In a round of Karaokey-Cokey, the audience were given The Funky Gibbon to hum. About three seconds in, Tim gets it and bursts out laughing.
    • A few panellists have also been tasked with accompanying themselves in Pick-Up Song, such as Tony Hawks singing along to Stutter Rap and Barry singing along to his cover of The Purple People Eater.
      • Barry's version of The Purple People Eater, which topped the Finnish charts, is referenced at other times:
    Humph: Barry once had a surprise number one in Finland, but then the cold weather does that to him.
    • When Richard Osman was a player in "Mornington Crescent", the game took on elements from Pointless.
  • Author Existence Failure:
    • Willie Rushton, one of the four regulars on the show since the 1970s, passed away in December 1996 due to complications from heart surgery. Since then, his spot has been filled by a guest for each episode.
    • Humphrey Lyttleton sadly passed away in early 2008. The show was very nearly cancelled afterwards until they went with a series of guest hosts, then settled with Jack Dee as host.
  • Defictionalization: Mornington Nomic is an attempt to construct an actual, playable version of "Mornington Crescent".
  • Keep Circulating the Tapes:
    • Owing to the nature of the programme's CD releases (each release contains four compilations rather than whole episodes), the only episodes that are commercially available in their entirety are the two Christmas specials. Some attempt seems to be made at rectifying this with the new "Live" range, which does release uncut recordings.
    • In a case of literal Keep Circulating the Tapes, whole episodes (but still without Pick-Up Song) were released on audio tape in the '90s.
  • No Budget: Mentioned in a round of Word For Word. Paul Merton buzzed Barry and Graeme, and Humph initially overruled his challenge, saying that they only had one buzzer and that was with Tim and Paul. He then says "...oh, thank you, Paul" as footsteps are heard, and then Graeme says "For those of you listening in stereo — it's over here now!" Later, when Barry challenges Tim and Paul, Paul says "we'd better have the buzzer back then, hadn't we?" and footsteps are heard again.
  • Screwed by the Lawyers: The "Pick-Up Song" round was excluded from any of the CD releases due to the cost of licensing the recordings for a long time. It finally appeared for the first time on the second Live release, and has since made its way into some of the compilation releases.
  • Throw It In!: Humph would occasionally misread something, and the improvisation by the panellists in response to this would usually be thrown in.
    • In another episode, Jack misread "Tobacconist's Film Club" as "Tobogganist's Film Club", before Graeme pointed out his mistake. The round turned into a mix of smoking puns and winter sports puns.
    • The sound once dropped significantly in the middle of a joke. Jack asked "Did the sound just drop then, on that?", and got answers of "Yes" from the panel and some of the audience.
    Jack: Oh good. I like to make sure, because otherwise Barry thinks he's having a stroke.
    Barry: I wish...
  • What Could Have Been: Due to Humph's unfortunate death, the regular trio of Graham, Barry and Tim were unsure if they wanted to continue, as were the producers. They eventually agreed to return for a series of guest hosts, then signed on again when Jack Dee was chosen as host.
