All the World's a Stooge (1941)

The stooges are window washers who lose their jobs after Moe impersonates the dentist in whose office they were cleaning. On the run, they are hired by a millionaire to pose as children. It seems the man's wife wants to adopt some refugees to impress her society friends. Moe is Johnny, Curly is Frankie and Larry is Mabel. Everything goes fairly well as the lady shows off the stooges to her friends, but they finally irritate her husband so much that he goes after them with an ax.
