For more on marking an answer as the "Best Answer", please visit our FAQ.I'm guessing it comes from the poster cmpaign during the war emphisising the need to keep information confidential - spies may be listening. One of the most famous posters had the message "Be like dad, keep mum." (I know but this was sixty years ago!) and to 'keep mum' was to stay silent. This, I assume was ebreviated to the 'Mum's the word'. If Quizzy knows better, and if ayone will he will, he'll be along shortly.
