* ActingForTwo:
** Creator/VickiLawrence has a blink-and-you'll-miss-it appearance, out of wig and costume, at the beginning of "Rashomama" as a nurse who walks past Naomi, Ellen and Eunice in the hospital (Mama herself is largely only seen through flashbacks in this episode).
** Lawrence has a significantly larger dual role in "Mama's Cousin", where she plays [[ExactlyWhatItSaysOnTheTin Mama's rich cousin]].
** Lawrence also made two appearances as Thelma Harper's mother -- once in a flashback sequence and once as a ghost.
* ActorAllusion: "Mama Sees Red" has Mama and the family playing a home game of ''[[Series/{{Pyramid}} The $25,000 Pyramid]]''. At one point, Mama tells Bubba to be Creator/DickClark, "but don't be a wiseacre." Vicki Lawrence was a frequent guest player on the show during this time, and was known for her on-air "feuds" with Clark (which on more than one occasion ended with her [[ScrewThisImOuttaHere leaving the set]]).
* ActorLeavesCharacterDies: Happens to Aunt Fran between the NBC and syndicated runs. This was because Rue [=McClanahan=] was involved with ''Series/TheGoldenGirls'', but it's unlikely she'd have wanted to return either way due to how she felt about her character (see WhatCouldHaveBeen below for more information).
* AnachronicOrder: "Alien Wedding" and "Mama's Silver" are set before Vinton is romantically involved with or married to Naomi, who is absent from "Mama's Silver", which was the first episode produced, with "Alien Wedding" produced second, with Naomi appearing as the Harpers' next-door neighbor. "Alien Wedding" and "Mama's Silver" aired near the end of Season 1, on April 2 and May 7, 1983.
* CaliforniaDoubling: For (presumably) Missouri. The house used as the front of the Harper house[[note]]beginning in season three[[/note]] is located in South Pasadena.
* CreatorBacklash:
** Creators Dick Clair and Jenna [=McMahon=] absolutely hated how Mama became more sympathetic during the series, as they had based the original sketches on ''Series/TheCarolBurnettShow'' on their frosty relationships with their own mothers.
** Harvey Korman reportedly hated doing the "Family" sketches on ''The Carol Burnett Show'', and only did the first two seasons of ''Mama's Family'' as a favor to Vicki Lawrence. This could possibly be the reason Alistair Quince and Ed Higgins are both absent from the syndicated run.
* CreatorsFavoriteEpisode: Vicki Lawrence has listed "Series/FamilyFeud", "The Wedding (part 2)", "Rashomama", "The Love Letter" and "Mama on ''Series/{{Jeopardy}}''" as her favorite episodes.
* TheDanza: Amy, Bubba's off-and-on girlfriend (and almost-fiancee) in season 4 was played by actress Amy Benedict.
* EditedForSyndication: The Alistair Quince introductions for the NBC episodes. In a more minor example, said episodes also used exterior shots of a different house for the opening (seen on the [=TimeLife=] DVD releases); for syndication, these shots were replaced with shots of the house used during the 1986-1990 run.
* IronyAsSheIsCast: While Mama is seen to be tone-deaf in "Flounder's Day", Vicki Lawrence herself is an accomplished singer, even having a hit with the 1972 song "The Night The Lights Went Out in Georgia".
* TheOtherDarrin:
** Roddy [=McDowall=] played Phillip Harper in the Carol Burnett sketches; when he declined to reprise the role for ''Eunice'', Ken Berry played Phillip instead.
** Carol Burnett refused involvement with the syndicated episodes due to her divorce from producer Joe Hamilton. Therefore, when Eunice called Mama one last time in season 4, Phyllis Franklin voiced the role in Burnett's absence.
** Thelma's late husband Carl was voiced[[note]]both times, the character was only heard in the bathroom and not seen[[/note]] by co-creator Dick Clair in the "1955" segment of ''Eunice'' and a flashback sequence in the season two episode "Mama's Birthday". After Clair's 1988 death, Ken Berry played him in a flashback sequence in the series finale.
* OutlivedItsCreator: The show itself managed to outlive just one of its creators -- Dick Clair, who died in December 1988. The other half, Jenna [=McMahon=], would pass in 2015, 25 years after the series finale.
* WhatCouldHaveBeen:
** Plans for a spin-off of the "Family" sketches had been discussed as early as Seasons 9-10 of ''Series/TheCarolBurnettShow''. Executive producer (and Burnett's then-husband) Joe Hamilton came to Vicki Lawrence with the news that he had made a deal to produce a weekly half-hour sitcom based on the sketches, but Lawrence -- who'd just given birth to her second child -- declined to participate, and the deal was off. It wasn't until the success of the "Eunice" special in 1982 that Burnett and Hamilton were able to convince Lawrence to do the series.
** Burnett decided to try for another spin-off idea when she and Hamilton divorced in 1984 (around the time ''Mama's Family'' ended its run on NBC). This resulted in Hamilton getting the rights to "The Family" sketches in the divorce terms, due to the fact that he was the executive producer of ''The Carol Burnett Show'' and helped write several of "The Family" sketches. Burnett phoned up Lawrence one day proposing a syndicated series featuring Eunice and Mama, but Lawrence told her she and Hamilton had already signed with [[Creator/{{Lorimar}} Lorimar-Telepictures]] (then the series' syndicated distributor) to relaunch ''Mama's Family'', causing Burnett to promptly hang up on her. The two actresses eventually reconciled following Hamilton's death in 1991.
** According to Rue [=McClanahan=], the original concept for Aunt Fran was radically different. Fran was initially conceived to be far more assertive and bossy, and would've served as the primary foil to Thelma. [=McClanahan=] had never before played a character of this type and eagerly signed on. She was bitterly disappointed upon learning that Fran had been re-written into a fussy, uptight spinster. Consequently, Rue did not enjoy her experience on the series that much and wasn't at all sorry when it was cancelled.
** The change to Fran's character apparently came about because of Naomi Oates. According to Creator/DorothyLyman, Naomi was first slated to be a gossipy, drop-in neighbor (similar to what Iola Boylan became, making the season four episode where the two characters switch personalities something of a DevelopmentGag). The role was redesigned into Thelma's trampy, tempestuous rival in order to provide a better showcase for Lyman. Vicki Lawrence and Carol Burnett were big fans of her performance as Opal Sue Gardner on ''Series/AllMyChildren'', and they chose her to play Naomi for this reason. As Rue [=McClanahan=] already had a signed contract, Fran had to be re-written.
