Dick Shawn (born Richard Schulefand, December 1, 1923 – April 17, 1987) was an American actor and comedian. He played a wide variety of supporting roles and was a prolific character actor. During the 1960s, he played small roles in madcap comedies, usually portraying caricatures of counterculture personalities, such as the hedonistic but mother-obsessed Sylvester Marcus in It's a Mad, Mad, Mad, Mad World (1963), and the hippie actor Lorenzo Saint DuBois ("L.S.D.") in The Producers (1967).
