Important Things with Demetri Martin is a sketch-variety show that aired on Comedy Central starring comedian Demetri Martin. Each episode examined a single theme, the "important thing", such as timing, power, control and money. All sketches, short vignettes, animated segments and stand-up comedy were loosely related to the theme of the episode. The show was produced by Jon Stewart's Busboy Productions, and contains stand-up, prop comedy and musical comedy by Martin, as well as taped sketches. Jon Stewart took an active role in editing the first few episodes.
