In the background of the study, as Maxwell and Niles are discussing Nanny Fine's shortcomings, a poster for My Fair Lady, from which the inspiration for this episode was drawn, can be seen.
Dorothy Lyman (Maureen Wentworth), most known for her acting work as 'Naomi Harper' in 'Mama's Family (1983)', directed 74 episodes of the series and appeared in another four episodes in uncredited roles.
Fran mentions that she got her proper accent mostly from 'Mrs. "Lovey" Howell' (Natalie Schafer), from 'Gilligan's Island (1964)', whose maiden name was 'Wentworth' (the same last name as the rich socialite at the party).
The title is based on the musical/movie My Fair Lady (1964) by Alan Jay Lerner and Frederick Loewe. The original Broadway production of "My Fair Lady" opened at the Mark Hellinger Theater in New York on March 15, 1956, and ran for 2717 performances, which was, at the time, the longest run a Broadway show had ever had.
