Jack Pearl

From Wikipedia

Jack Pearl, born Jack Perlman (October 29, 1894 – December 25, 1982), was a vaudeville performer and a star of early radio.

Born in New York, Pearl made an easy transition from vaudeville to broadcasting when he introduced his character Baron Munchausen on The Ziegfeld Follies of the Air in 1932. His creation was loosely based on the Baron Münchhausen literary character. As the Baron, Pearl would tell far-fetched stories with a comic German accent. When the straight man (originally Ben Bard, but later Cliff Hall) expressed scepticism, the Baron replied with his familiar tagline and punchline: "Vass you dere, Sharlie?" This catch phrase soon became part of the national lexicon.
