One Run Elmer is a 1935 American short comedy film featuring Buster Keaton, and directed by Charles Lamont.
One day a family of ruthless businessmen show up and erect their own gas station directly opposite Elmer's and begin competing with him.
Elmer, fueled by jealousy challenges the businessmen to an impromptu baseball practice and is quickly outclassed.
During the game, both men resort to cheating, with the businessman tying the home base to his ankle so he can drag it closer to him, and Keaton using a bat twice its regular size.
The conclusion of the game comes when Elmer steals a bullet from a nearby policeman's holster and places it inside his bat.
