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 produced as a contingency in the event of cricket coverage running shorter than anticipated and were never aired. (Both episodes were one-offs featuring former contestants.)
Sometimes it's possible to create an odd number out of only even numbers. This begins with a division equation (such as 6/2 for 3 or 100/4 for 25); this newly-created odd number can then be added to or subtracted from whatever numbers are made out of the remaining equations.
