Lou Ferrigno, who's 54, was sworn in during a ceremony Monday night. He tells The Associated Press his father had been a New York City police officer, and he's always had a high respect for officers.
Ferrigno began training to become a reserve deputy last September after passing a background check. He will serve at least 20 hours a month, help recruit new deputies and work with the sheriff's Youth Activities League and the Special Victims Bureau, which assists abused children.
Ferrigno played the green-skinned Hulk on the CBS-TV show from 1977 to 1982.
