After gaining fame as The Fonz's cousin Chachi on Happy Days, Scott Baio (pictured in 1984) played Charles, the relentlessly likable college student/live-in manny to three lovably feisty kids. Since then, Baio has popped up in many TV shows and films, but his most notable recent character was Bob Loblaw, the Bluth family lawyer in Arrested Development. (You pronounce it Bob Blah Blah.) He also had a VH-1 reality show, Scott Baio is 45…and Single, and its successor, Scott Baio is 46…and Pregnant. Despite these shows, Baio's still "Chachi" in the national consciousness. "If somebody's gonna call me Chachi to break my balls, then I got a problem," he told Entertainment Weekly. "Otherwise I don't care. Most people are just generous and sweet."
