James Maritato (born March 12, 1972) is an American professional wrestler, best known for his work in Extreme Championship Wrestling (ECW) and World Wrestling Entertainment (WWE) under the ring names Little Guido and Nunzio. A high-school football player and amateur wrestler, he trained under Billy Robinson, making his professional debut in the early nineties. He joined Eastern Championship Wrestling initially as an enhancement talent, as well as competing in the shoot style UWF International promotion. Maritato later returned to ECW (now Extreme Championship Wrestling), being given the gimmick of “Little Guido” as part of the comedy stable the Full Blooded Italians (F.B.I). He would stay with the promotion until its closure in January 2001.

After ECW closed its doors, Maritato worked on the independent circuit before he was signed to a contract by WWE in 2002. There he was part of the promotion’s cruiserweight division until its disbandment in 2007, as well as a new version of the F.B.I Stable. He would take part in the ECW One Night Stand events as well as the relaunch of the franchise as a third brand before leaving WWE and returning to the independent circuit.

While attending Nanuet Senior High School (located in Rockland County, New York), Maritato competed in football (as part of the school's 1989 team that went undefeated and unscored upon) and wrestling.

Maritato was trained as a professional wrestler by Billy Robinson. He debuted in 1991, facing Parsippany Smith Fields in his first match. He competed for the Amarillo, Texas-based USWF promotion under the name James Stone.

Maritato joined Eastern Championship Wrestling (ECW) under the ring name "Damien Stone" on July 14, 1992, where he lost to Tommy Cairo. Over the next two years, he wrestled intermittently with ECW as a jobber. He also wrestled for International World Class Championship Wrestling and other promotions in the Northeastern United States.

Maritato took some time off from ECW in 1995 and went to Japan to compete in the shoot style UWF International promotion.

Maritato returned to Eastern Championship Wrestling - by now known as Extreme Championship Wrestling - at the Big Ass Extreme Bash in March 1996. At Massacre on Queens Boulevard in April 1996, "The Italian Stallion" J.T. Smith announced that "Damien Stone" was in fact his Sicilian cousin, "Little Guido". Smith and Little Guido formed the comedy stable Full Blooded Italians (F.B.I.), which grew to include multiple other members.

During 1999, he became a "serious wrestler", although still accompanied by Sal E. Graziano and proclaiming himself to be an F.B.I. member (though only the two of them were left). After his turn he was involved in some intense singles matches until late 2000, when he formed a tag team with Tony Mamaluke. The duo won the World Tag Team Championship on August 26, 2000 and held them until December when they lost them to Danny Doring and Roadkill. They continued to wrestle together until ECW folded in January 2001.
