Ted McGinley

When Ted McGinley joined the ABC show Dancing with the Stars in 2008 he was billed as the "sitcom scene-stealer," a reference to his long career in sitcoms, from Happy Days to Married With Children. McGinley's big break came when he joined Happy Days for its final seasons, from 1980 to 1984 (the show began in 1974). He's worked steadily in television ever since, from The Love Boat (1984-86) to Hope & Faith (2003-06; he played Megan Fox's dad in the show). Although cinés know McGinley for his role as the fair-haired fratboy in Revenge of the Nerds (1984), he's probably best known for his turn as Jefferson D'Arcy, Al and Peg Bundy's friendly neighbor, in seven seasons of Married with Children (1991-97).
