A sketch comedy consists of a series of short comedy scenes or vignettes, called "sketches," commonly between one and ten minutes long. Such sketches are performed by a group of comic actors or comedians, either on stage or through an audio and/or 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.

An individual sketch or vignette is a brief scene or skit formerly used in vaudeville and used today on variety shows, comedy programs, adult entertainment, talk shows, or certain children's television series (such as Sesame Street). Such a sketch can include footage of a "man on the street", pioneered by American television personality Steve Allen on evening comedy television programs like The Tonight Show.

More serious sketch comedians differentiate their art from that of the skit, maintaining that skits tend to be a (single) dramatized joke, while a sketch is a comedic exploration of a concept, character, or situation.

James Hugh Calum Laurie, OBE (born 11 June 1959), known as Hugh Laurie (/ˈhjuː ˈlɒri/), is an English actor, voice artist, comedian, writer, musician, recording artist, and director. He first became known as one half of the Fry and Laurie double act, along with his friend and comedy partner Stephen Fry, whom he joined in the cast of Blackadder and Jeeves and Wooster from 1987 to 1999.

From 2004 to 2012, he played Dr Gregory House, the protagonist of House, for which he received two Golden Globe awards, two Screen Actors Guild awards, and six Emmy nominations. As of August 2010, Laurie is the highest paid actor in a drama series on US television. He has been listed in the 2011 Guinness Book of World Records as the highest paid actor ever in a TV Drama—earning US$ 700,000 per episode in House—and for being the most watched leading man on television.

Laurie was born in Oxford, Oxfordshire, England. The youngest of four children, Laurie has an older brother named Charles and two older sisters named Susan and Janet. He had a somewhat strained relationship with his mother, Patricia (née Laidlaw).
