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 and as Marty Funkhouser in Curb Your Enthusiasm).
