Final appearance of Isabel Sanford on the show.
This episode marks Richard Ward's last television appearance,as the actor passed away three and a half months after this episode aired.
The first appearance of Janet MacLachlan's "Polly", who would appear in a total of 4 episodes (3 on "Archie Bunker's Place"). While her character remained the same, her surname would go from "Lewis" to "Swanson" for the final 3 appearances.
In the first scene Edith says to Archie "Guess who's coming to Breakfast?". The film Guess Who's Coming to Dinner (1967) depicts the story of a mixed race couple who surprise her parents by showing up with her fiance who happens to be African-American. Much like those parents Archie must confront and overcome (ever so slightly) his own preconceived notions about race. Isabel Sanford had played the family servant on that film, whose character uttered the film's title.
Oddly, the Bambinis apparently sold the house back to the Jeffersons, having bought the place when Mike nabbed the job in California.
