Their catchphrase, as I recall it, was (more in keeping with their image), "Play the game, you cads", together with frequent references to "The old school tie".

"Get up them stairs" was indeed a popular phrase of the day, much used among us schoolchildren in about 1943 to mean something like "Get away with you, don't talk such nonsense". But I still can't racall with which radio act it originated. I don't think it was any of Tommy Handley's ITMA associates.
