Stand-up comedy is a comedic performance to a live audience in which the performer addresses the audience from the stage. The performer is known as a comedian, comic, or stand-up. It is usually a rhetorical performance, but many comics employ crowd interaction as part of their routine. Stand-up comedy consists of one-liners, stories, observations or shticks that may incorporate props, music, magic tricks, impressions or ventriloquism. It can be performed almost anywhere including comedy clubs, comedy festivals, bars, nightclubs, colleges or theaters, however, it is best suited to the controlled environment of a purpose-built comedy club.
