Phony Express (1943)

Set in the old west, the stooges are three tramps wanted for vagrancy. After ruining a medicine peddlers show, they arrive in Peaceful Gulch where a picture has been printed declaring them to be three famous lawmen coming to clean up the town. Assigned to guard the bank, the boys have the local gang scared at first, but when the gang learns who the stooges really are, they rob the bank. The boys go in pursuit, find the bad guy's hideout, subdue the bandits and recover the money. Written by Mitch Shapiro
