The Split Sides comedy club in Grand Theft Auto IV as well as its DLCs hosts a number of real life comedians who conduct routines in front of live audiences. Only one guest is feature in each visit, and the sequence of acts are repeated after all a certain amount of visits. Originally, GTA IV features only two comedians: Ricky Gervais and Katt Williams. For The Lost and Damned, however, Frankie Boyle is included as an additional guest exclusively for the DLC. Routines by Ricky and Katt have also been featured on Weazel, a fictional television channel in the game.
A real life English comedian, actor, and film maker, most known for his role in British comedy series "The Office (UK)" and the 2009 comedy film "The Invention of Lying". He is also known for his podcast and now TV Programme The Ricky Gervais Show.
A real life American comedian, rapper and actor. In addition to his appearances in the Split Sides, Katt was also interviewed in a Weazel News report as he is participating in a protest related to drugs. Katt is nicknamed "The Pimp" by the introduction narrator. One of his Split Sides routines, "Hustlin'" is a recreation of one of his popular real-life routines and the Rick Ross song featured in the routine (and also as Williams' introduction music in the other routines) was licensed for the game. In another of his routines, Williams pokes fun at "the other club", likely referring to Perestroika.
