Mr. Muggs Steps Out is a 1943 American comedy film directed by William Beaudine and starring The East Side Kids.

[1] Much to the despair of her husband John, wealthy New York socialite Margaret Morgan hires former criminals Masie O'Donnell and Butch Grogan to be her house servants.

At the end of the evening, one of the guests discovers that her diamond necklace is missing, and John accuses the East Side Kids of the theft.

However, everyone recalls seeing a stranger at the party, whom Maisie now remembers as someone she met at Danceland, a dance hall on the lower East Side.

Nolan becomes suspicious when naïve Virgil, who has followed Brenda to the dance hall, uses her real name and asks him to throw a fake fight so that he can prove his manhood.
