“Never give a sucker an even break.”
According to Collier's (28 November 1925), Fields is said to have used this line as early as 1923 in the musical comedy play Poppy. It became the title of one of his films in 1941 (and Fields' character also spoke this line in the sound film version of Poppy [1938] and in You Can't Cheat an Honest Man [1940]).
