Although never scripted, his catchphrase was generally known as "My name is Harry Worth. I don't know why – but, there it is!" It was really invented by impressionists of the day to give a common ground tag line to work with. One running joke in the television show involved references to Harry's never seen aunt known only as "Auntie", the popular nickname for the BBC itself. In one show, Harry commissioned a portrait of Auntie, only to receive a head-and-shoulders print of a woman with no face. He was the subject of "This Is Your Life" in October 1963 when he was surprised by Eamonn Andrews at Manchester's Gaumont cinema.
