D'Auria is best known for his role in WGN-TV Chicago's The Bozo Show from 1984 to 2001. D'Auria was hired after a long search for the next Bozo in part because his improvisational skills were very good.[2][3] D'Auria also blended well with Roy Brown, who said he knew right away that D'Auria would be a hit after telling him he had broken his arm in three places and getting a response of, "Then don't go in those three places!" D'Auria played Bozo until the show's cancellation in 2001.
