Jimmy is an actor who appears on the radio in both Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. In 1986, as a child actor, he starred in the show Just the Five of Us, alongside Claude Maginot, playing a child of the same name. His catch phrase on the show was "But I'm 42!", going on to say that he has "a rare disease" and is an investment banker as well as sexually active. By 1992, however, the show has been cancelled and replaced by My Five Uncles.
In 1992, he attends a child actor's convention at The Four Dragons Casino in Las Venturas (sometime after the mission The Meat Business), and is arrested for cocaine. While being dragged out, he insists it's "just flour, I swear!", and punches Richard Burns in the groin, calling him a "liberal media bastard". He mentions that he is 51 years old.
