In 'A Busy Day', Charlie Chaplin (in drag) plays a wife jealous of her husband's (Mack Swain) interest in another woman. On her way to attack the couple, the wife interrupts the set of a film, knocking over a film director, played by Mack Sennett, and a police officer, played by Billy Gilbert. Finally, the husband pushes Charlie Chaplin off of a pier, where he/she falls into a harbor.
