Skits/Sketch comedy
Sketch comedy consists of a series of short comedy scenes, or 'sketches', commonly between one and ten minutes long. Such sketches are performed by a group of comedic actors, either on stage or through an audio or/and visual medium such as broadcasting. Often sketches are first improvised by the actors and written down based on the outcome of these improv sessions, however improvisation is not necessarily involved in all sketch comedy.
A play is a story that is written to be acted on a stage or in a theater. A skit is a short play that is usually performed in a more informal setting like a club meeting or a classroom. Skits are often funny. Acting is to perform, to play a part, to pretend to be a character in a play for theater, a movie, television or radio. The written text for a skit or play is called the script.
