Visual gag

In comedy, a visual gag or sight gag is anything which conveys its humour visually, often without words being used at all. The gag may involve a physical impossibility or an unexpected occurrence. The humor is caused by alternative interpretations of the goings-on. Visual gags are used in magic, plays, and acting on television / movies.

Types

The most common type of visual gag is based on multiple interpretations of a series of events. This type is used in the 1935 Alfred Hitchcock film The 39 Steps. Lead actor Robert Donat was kidnapping actress Madeleine Carroll and they were handcuffed. When they checked into an inn, the innkeeper assumed that they were passionate lovers because of the handcuffs. The film used dialogue that could be interpreted both ways.

Another visual gag is a switched image, often at the beginning of a film. A subsequent view of the scene shows something not viewed before. Switched movement may be the gag, such as Charlie Chaplin in The Pawnshop. Chaplin fights with his coworker and punches at him once. Their boss walks in mid-swing and Chaplin changes the motion to act like he was dropping to his knees to scrub the floor.
