What age did US comedian Jack Benny always claim to be?

Jack Benny (born Benjamin Kubelsky; February 14, 1894 – December 26, 1974) was an American entertainer, who transitioned from modest success playing violin on the vaudeville circuit to a highly popular comedic career in radio, television, and film. He was known for his comic timing and the ability to cause laughter with a pregnant pause or a single expression, such as his signature exasperated "Well!"

His radio and television programs, popular from 1932 until his death in 1974, were a major influence on the sitcom genre. Benny often portrayed his character as a miser, who obliviously played his violin badly, and ridiculously claimed to be 39 years of age, regardless of his actual age.

Benny also starred in several movies, including "The Hollywood Revue of 1929" (1929), "Broadway Melody of 1936" (1935), "The Horn Blows at Midnight" (1945) and "George Washington Slept Here" (1942), although he had much greater success on radio and on TV than he did on the big screen.

He was good friends with Fred Allen, with whom he had a long-standing comic "feud". In trying to explain his successful life, Benny summed it up by stating: "Everything good that happened to me happened by accident. I was not filled with ambition nor fired by a drive toward a clear-cut goal. I never knew exactly where I was going."
