Joey Faye (July 12, 1909 – April 26, 1997) was an American comedian and actor, born Joseph Antony Palladino in New York City. He gained fame as a comic in vaudeville and claimed he created two of vaudeville's more renowned pieces of business, "Floogle Street" (a.k.a. "Susquehana Hat Company" on YouTube) and "Slowly I Turned".[1] In addition to an active career in vaudeville and the legitimate theater, he appeared in many movies and TV shows.[citation needed]
