Phony Express (1943)

When Red Morgan and his gang invade Peaceful Gulch, the local editor prints a picture of the Stooges (who are wanted for vagrancy) as three famous marshals coming to clean up the town. When the Stooges show up in town, Red and his gang are worried until they find out the Stooges are just tramps, but when the gang tries to get them the Stooges manage to kncok them out instead. The boys get hired to guard the bank, but when Morgan and his gang rob it anyway, it's up to the Stooges to get the gold back!
