The show was originally filmed in Carefree, Arizona in order to accommodate Van Dyke who was living in Arizona at the time. For the third season, production was moved to Hollywood. Van Dyke decided not to continue with the show because he wanted to move back to Arizona and because Carl Reiner had quit as producer.
Carl Reiner wrote an episode in which Jenny was to walk in on Dick and Jenny having sex. When CBS refused to air the episode, Reiner protested by stating he would never work with CBS again after the third season. But Reiner returned to CBS in 1981 to appear in The Magical World of Disney: Walt Disney: One Man's Dream (1981) and Skokie (1981). The episode aired in syndicated reruns.
