The Knockout on AllMovie

Although better known as Charlie Chaplin's 17th appearance in a Keystone comedy, The Knockout is really a Roscoe "Fatty" Arbuckle film. The big event in Fatty's town is a prizefight in which champ Cyclone Flynn will meet all comers. Fatty is tricked into accepting the fight by two hobos who are making book on the fight. Through a note ostensibly from Flynn, they offer Fatty a split if he throws the fight, but Fatty, thinking one of the hobos is Flynn, refuses. The real Flynn arrives and dispatches the impostors. The match proceeds with heavy betting going on and Fatty's girlfriend dressed as a boy in order to gain entrance to the arena. Charlie is the referee who is constantly being knocked down by the fighters because he keeps getting in between them. Angered by losing after a short count, Fatty grabs two six-guns from a gambler at ringside and begins firing in all directions. Cyclone takes to his heels and a classic rooftop Keystone chase ensues, with the Keystone Kops in pursuit of Fatty, in pursuit of Cyclone. When the Kops lasso Fatty, he drags six of them along the ground by the rope until he leaps off a pier taking them all with him. With everyone treading water, the Kops surround Fatty as the film ends.
