Harry Einstein (May 6, 1904 – November 24, 1958), known professionally as Harry Parke and other pseudonyms, most commonly Parkyakarkus, was an American comedian, writer, and character actor. A specialist in Greek dialect comedy, he became famous as the Greek chef Nick Parkyakarkus on the Eddie Cantor and Al Jolson radio programs, and later on a program of his own. He appeared in eleven films (as Parkyakarkas or a close variant) from 1936 to 1945. He was also the father of comedians and actors Albert Brooks and Bob Einstein (who performed as Super Dave Osborne).
