GM Grimm

Percy Carey, also known as MF Grimm, GM Grimm, The Grimm Reaper, and Superstar Jet Jaguar, is an underground rapper from New York City. As a child, Percy Carey grew up on Manhattan's Upper West Side in a stable family. His neighbor, the famous black actor, Morgan Freeman helped arrange for him to be cast as a child actor on Sesame Street, which he did for four years. "One episode, I lost my tooth, and me and Big Bird had to go through Sesame Street and try to find it," Carey remembers.[1]
