Fourth Wall

Breaking the fourth wall is a comedy device (also a running gag) used in fictional stories in which a character acknowledges the fact that they are a character in a show or television show, and are actually aware of being such, and tell the audience. This violates the separation between the character and the audience, the convention being known as the fourth wall. There are several ways of breaking the fourth wall; examples include when a character refers to a particular part in a television episode, when a character stops others from performing an occult or criminal act by referring to the fact that it is a "children's movie/show," when a character responds to a real world person who is not physically present (such as the narrator), or when a character talks directly to the viewer.
