Stand-up comedy is a style of comedy where the performer speaks directly to the audience, with the absence of the theatrical "fourth wall". A person who performs stand-up comedy is known as a stand-up comic, stand-up comedian (comedienne if female) or more informally stand up. It is usually performed by a single comedian, with the aid of a hand-held microphone. The name comes from the fact that the comic usually stands up during their routine. The comedian usually recites a fast-paced succession of humorous stories, short jokes (called "bits"), and one-liners, which comprise what is typically called a monologue, routine or act. Some stand-up comedians use props, music or magic tricks to enhance their acts. Stand-up comedy is often performed in comedy clubs, bars, colleges and theaters. However, there is no real restriction on where the craft can be performed. Many smaller venues hold "open mic" events, where amateur comedians perform comedy before a live audience, offering a way for such performers to hone their craft and possibly break into the business. In North America, many comedy clubs feature the now-iconic brick wall as the backdrop for stand-up performances. .
