"Professor" Irwin Corey was an American stand-up comic, film actor and activist, often billed as "The World's Foremost Authority". He introduced his unscripted, improvisational style of stand-up comedy at the San Francisco club the hungry i. Lenny Bruce described Corey as "one of the most brilliant comedians of all time."

The Hungry I was a nightclub in San Francisco, California, originally located in the North Beach neighborhood. It played a major role in the history of stand-up comedy in the United States. It was launched by Eric "Big Daddy" Nord, who sold it to Enrico Banducci in 1951. The club moved to Ghirardelli Square in 1967 and operated mostly as a rock music venue until it closed in 1970.
