After having directed some episodes of The Dick Van Dyke Show in which he played the recurring character of next-door neighbor and dentist Jerry Helper, Paris won an Emmy Award in the 1963-64 season for Outstanding Directorial Achievement in Comedy for that classic series. He later devoted himself to directing both in film and television, including The Partridge Family and Here's Lucy (including the famous third season opener featuring Elizabeth Taylor and Richard Burton), but he worked most notably on the 50s nostalgia television series Happy Days, for which he directed 234 of the show's 255 episodes. The show was a bona fide No.1 hit in the late 1970s and he was effectively the show's house Director. Imitating Hitchcock, he appeared uncredited in at least one episode of every season.
