Back Stage is a 1919 American two-reel silent comedy film directed by and starring Roscoe "Fatty" Arbuckle and featuring Buster Keaton and Al St. John.

In this film, Keaton, Arbuckle, Al St. John, and others work back stage as stagehands in a playhouse trying to help out and, in some cases, stay away from the eccentric performers.

But upon returning inside the theatre he unwittingly leaves the door open so it obscures the left side of the sign and appears to read:

The staff attempt to defend the assistant but the strongman is so powerful that he is able to blow Fatty away using only his breath and does not even flinch when Keaton repeatedly hits him over the head with an axe.

Eventually the staff manage to subdue the strongman by challenging him to prove his immense strength by lifting a heavy weight then electrocuting him.
