When introducing his father Cliff says "this is my younger brother Russell Huxtable". In real life Bill Cosby actually has a younger brother named Russell.
If you notice, the home of Mrs. Hickson is the same home used for Col. Taylor in various episodes of A Different World.
For her work in this episode, Eileen Heckhart was nominated for an Emmy for Outstanding Guest Performer in a Comedy.
Bill Cosby and Keshia Knight Pulliam appeared on A Different World later in the evening.
