Related to the game show:
- Fan Nickname: Richard Whiteley used to be nicknamed "Twice Nightly" Whiteley by Yorkshire Television viewers- whether or not any Double Entendre was intended, it was due to the fact he also used to present the local news programme Calendar as well as the game show within the same evening.
- Missing Episode: A pair of episodes were allegedly produced as a contingency in the event of cricket coverage running shorter than anticipated and were never aired.
- Never Work with Children or Animals: On an 8 Out of 10 Cats Does Countdown episode, Jimmy Carr's attempt to distract the panel with two baskets of four kittens each (get it?) quickly went south when he couldn't control them.
- What Could Have Been: A pilot for a U.S. adaption was made; details are here. It notably disposed of the numbers round, and had celebrities playing with the contestants; it's not surprising that Jon Peters, a producer synonymous with Executive Meddling, was at the helm here (though it's because he acquired Chuck Barris Enterprises shortly before; he ended up selling it to what's currently Sony Pictures Television).
