 A regular feature on the programme, preceding the game Mornington Crescent, is a fictional letters section which begins with the chairman's comments ("I notice from the sheer weight of this week's postbag, we've received a little over no letters" and "I see from the number of letters raining down on us this week that the Scrabble factory has exploded again").The invariably single letter each week is from "A Mrs Trellis of North Wales", one of the many prompts for a cheer from the audience, whose incoherent letters usually mistake the chairman for another Radio 4 presenter or media personality.
