Britain's Got Talent - c. 1943

"A broad Brummie got up on stage and Ralph [Reader - leader of the Gang Show and mentor of Tony Hancock] said: "What do you do?"

"He said: "I jump."

"Ralph said: "No.  What's your act?"

"He said: "That's my act.  I jump."

"Ralph said: "What do you mean, you jump?"

"He said: "Well, I jump and get higher and higher.  That's what I do."

"He then stood to attention and he jumped and he jumped and he got so high.

"It became a standing joke between the two of us.  If I phoned him and he asked: "Who's that?", I would always say: "I jump."

"He always knew who it was then, and we were away."

(Friend of Tony Hancock, as quoted in Tony Hancock: The Definitive Biography by John Fisher)
