Scott Baio's career began when he beat out thousands of teenagers to nab the lead role in the 1976 film version of Bugsy Malone which starred all children (including a young Jodie Foster as Tallulah). He made his name as Chachi in Happy Days and in the spin-off Joanie Loves Chachi. He later played the title role in Charles In Charge and after quitting his part as Jack in Diagnosis Murder he played a lead role in Danielle Steele's Mixed Blessings (1996).

He was born in Brooklyn, New York and his birthday is September 22, 1961.
