In a 2002 Mary Tyler Moore Show Reunion Special, Betty White said that this episode was her favorite.
One of the episodes of The Mary Tyler Moore Show that MeTV aired in a tribute to Betty White following her passing on December 31, 2021.
Sue Ann indicates she is five years older than Lila - although later it's indicated Lila stole Sue Ann's boyfriend while Sue Ann was in high school (which would be quite a feat for a 12-year-old!) In real life, actress Betty White (Sue Ann) was 14 years older than Pat Priest, who played Lila.
Pat Priest guest stars as Lila, sister to Sue Anne Niven (Betty White). Priest played Marilyn Munster on the iconic TV sitcom The Munsters (1964-1966).
