By the time taping started on the third season in 1987, Jackée Harry, who had just won an Emmy for Outstanding Supporting Actress, changed her stage name to simply Jackée, which she used until 1994. In the fourth season, an 11-year-old child prodigy named Alexandria DeWitt (Countess Vaughn) became the Jenkinses' houseguest. Vaughn received her role after she appeared on "Star Search" and declared to host Ed McMahon that her favorite show was "227". However, Alexandria left during Calvin's graduation episode near the end of season four to reunite with her father who, after completing his archaeological dig in the Amazon, had moved to London to catalogue his items.
