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.
