!! The NBC Series

* ActingForTwo: Music/MCHammer as the flamboyant Reverend Pressure and as himself in the episode "Three Men And A Hammer".
* ActorAllusion:
** In one of the show's Christmas Episodes, the choir is bickering over which song to sing for a competition. When someone suggests "Mary's Boy Child", Rolly scoffs at the idea, claiming "I never cared for that one." The song [[MythologyGag was actually written by Rolly's actor Jester Hairston]]. Later in the episode, [[TheCastShowoff he sings it during the competition]].
** As cited above, Music/MCHammer is an ordained minister, meaning he was essentially playing himself twice in his appearance. In fact, his character Reverend Pressure has the same name as the character he played in the movie ''Please Hammer Don't Hurt Him: The Movie'', and probably ''is'' the same person.
* KeepCirculatingTheTapes: No plans to be released on DVD, though reruns can be seen daily on Encore Black. Also terrestrial channel Get TV has begun airing the series as of January 2, 2019.
* ThoseTwoActors: [=LaWanda=] Page and Whitman Mayo of Series/SanfordAndSon turn up for several episodes in the final season as a bickering married couple.
** Creator/LynneMoody appeared in the first season as a love interest of Reuben's, after playing a pre-''Series/TheJeffersons'' Jenny Willis on ''Series/AllInTheFamily'', and later appearing on the former -- where she costarred with Sherman Helmsley, and playing Clifton Davis' (Reuben Gregory) sister Tracy on the 1974-1975 sitcom ''That's My Mama'', which also starred Jester Hairston (Rolly) as Wildcat.
* YouLookFamiliar: John Hancock appears in the pilot episode as the church's minister, who quits after a clash with Ernie. He reappears in the final season episode "My Fair Homeboy" as a business partner of Ernie's.
