The title of the film is from a catchphrase used by Red Skelton on his radio show when he was in character as the "Mean Widdle Kid".
According to M-G-M press materials, Buster Keaton served as technical advisor for some of the slapstick scenes in this film. It is a loose remake of Spite Marriage (1929) which starred Keaton in his second film under contract to M-G-M and his last silent film. Indeed, Red Skelton seems to exactly mimic many of Keaton's gags from the earlier film.
This film used two of Eleanor Powell dance routines from earlier movies. They were the Hula from Honolulu (1939) and the Battleship routine from Born to Dance (1936).
It's Jimmy Dorsey's younger brother Tommy himself whom Red says has too many violins, when asked in front of the nightclub. He makes a similar appearance in one of Kay Kyser's films.
