Additional information

Behind the scenes three was company until fall 1980, when Somers and her husband/manager, Alan Hamel, asked for a raise from 30,000 per episode to 150,000 per episode plus 10% of the show's profits. Co-stars Ritter and DeWitt, confused and angry, refused to work with Somers, whose role was reduced to a phone-call from a separate soundstage at the end of each episode (Chrissy had been sent to take care of her ailing mother in Fresno). For the remainder of the 1980-81 season, Jenilee Harrison performed as a "temporary" roommate, Chrissy's clumsy cousin Cindy Snow. By fall 1981, Somers was officially fired, and Priscilla Barnes was cast as a permanent replacement, playing nurse Terri Alden, a more sophisticated blonde (Harrison's character moved out to attend UCLA but occasionally visited through spring 1982).

Jenilee to replace the national phenomenon in the role of Chrissy's cousin, Cindy Snow. The producers soon learned their lesson and diminished Jenilee's participation on the show as she failed to register on the jiggle meter. Jenilee still appeared on the show as she was relegated to contract-fulfilling walk-ons.
