Jimmy is an actor who appears on the radio in two games: Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. In 1984, 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. The show was still on the air and widely popular in 1986. However, by 1992, the show had been cancelled and replaced by My Five Uncles. In 1992, he was also arrested for possessing drugs, probably cocaine as he said that it was "just flour, I swear!" during his arrest, and told Richard Burns, who briefly interviewed him for WCTR News that he was fifty-one years old.
Jimmy is a reference to Emmanuel Lewis of Webster's dwarfism and late Gary Coleman's kidney condition, which makes both actors look like small children even though they were both 39 and 42 as of 2010.
