Four years later, Brennan and Chappelle came together to co-create, co-write and co-executive produce the eponymous sketch comedy "Chappelle's Show", which premiered in January 2003. Brennan said that he and Chappelle read the book "Live from New York: An Uncensored History of Saturday Night Live" (2002), by Tom Shales when they started writing sketches for the show, and found the book very helpful. The duo wrote the show's sketches with minimal outside help and agreed never to divulge who was responsible for writing which sketch.
