Lonny Ross

Biography: Best known as Josh, the less-than-brilliant "house impressionist" of "The Girlie Show" (and definitive off-camera schemer) on NBC's smash-hit sitcom 30 Rock -- the slightly goofy-looking and hangdog-faced character actor Lonny Ross established a distinctive comedic presence when he emerged in the mid- to late 2000s. Rock represented Ross' big break; he then parlayed his small-screen triumph into movies, with small supporting roles in the Jessica Alba/Dane Cook romantic comedy Good Luck Chuck (2007) and the Paul Soter-directed farce Watching the Detectives (2007).
