After Fred strolls through the house singing "Jelly Jelly," Lamont sarcastically asks him if he thinks he's Billy Eckstine. Eckstein himself would guest star and sing the same song in the fourth season episode "The Stand-In."
Redd Foxx (as Uncle Budd), Emily Yancy (as Mable) and Demond Wilson (extra in crowd scene) all appeared in the 1970 film Cotton Comes to Harlem.
Emily Yancy (Alice) plays the part of Ja'net DuBois' daughter, despite there only being seven years between their ages (DuBois born in 1932, Yancy in 1939).
Fred at one point claims that he looks "good enough to be on the cover of Ebony." Redd Foxx actually appeared on both the July 1972 and June 1974 covers of Ebony Magazine.
