* ActorAllusion: In "Brotherly Love", Dorothy recounts how while on a double date with Stan and his brother at a soda shop, Stan "entertained" them by sticking straws up his nose and pretending to be a walrus. In the "Cousin Maude" episode of ''Series/AllInTheFamily'', Arthur's character Maude recalls Archie Bunker doing the same thing on a double date with her cousin Edith and herself.
** One of the songs that Dorothy sings at the Rusty Anchor in the final season episode "Journey to the Center of Attention" is "Hard Hearted Hannah (The Vamp of Savannah)" (from ''Tin Pan Alley''), which Bea Arthur had previously sung in an episode of ''Series/{{Maude}}''.
* DawsonCasting: Inverted with Sophia. Creator/EstelleGetty was actually the second youngest cast member.
* FakeNationality[=/=]CastingGag: In keeping with the precedent set by the casting of Dorothy and Sophia, every prominent Italian on the series was played by a Jewish actor.
* HeyItsThatGuy: In addition to an array of guest stars that included the likes of Dick Van Dyke and Leslie Nielsen, some young stars who [[RetroactiveRecognition weren't yet famous]] made appearances in episodes, including [[SavedByTheBell Mario López]] as [[TheDanza Mario]], a prized student of Dorothy's in danger of deportation, and child-star-turned-indie-rock-star [[RiloKiley Jenny Lewis]] as Daisy, a Sunshine Cadet who holds Rose's beloved childhood teddy bear hostage. [[Series/StarTrekVoyager Robert Picardo]] plays a surgeon with a terrible bedside manner. Creator/GeorgeClooney, Creator/QuentinTarantino, and BobHope also make appearances.
** [[{{Series/Maude}} Maude and Vivian]] are now living together, [[TheMaryTylerMooreShow Sue Ann Nivens]] is dating [[TheMaryTylerMooreShow Rhoda's father]], and [[TheMaryTylerMooreShow Rhoda's mother]] is Sophia's sister.
* TheOtherDarrin: ''Lots''. From Dorothy's sister Gloria, to Blanche's daughter Rebecca, to Rose's daughter Kirsten, and even the cast of the episode that was a pilot for the spin-off series ''Empty Nest''.
** The ''Empty Nest'' example might not count, since the entire ''plot'' changed between the PoorlyDisguisedPilot and the actual series. In the pilot, the story was about a middle-aged married couple learning to reconnect and begin a new part of their life after their youngest daughter leaves for college (an actual "empty nest.") In the spin-off show, the main character was Harry, who had been established as a recurring character on ''The Golden Girls'' - a pediatrician who lived near the title characters. Harry was a recent widower whose self-supporting adult daughters move back in with him (creating something of an ArtifactTitle.) None of the characters from the pilot actually made it to the show with the exception of David Leisure as the DropInCharacter neighbor, and even he was changed from a pilot named Oliver to a cruise ship employee named Charlie. The house in which the pilot was filmed was the only other thing carried over to the actual series.
* [[PhallicWeapon Phallic Object]]: The questionable penis-shaped tin in the kitchen is actually a lobster.
* PlayingAgainstType: Rue [=McClanahan=] and Betty White were supposed to play Rose and Blanche, respectively. They suggested switching around. Betty White was well-known for playing "Happy Homemaker" Sue Ann Nivens on ''TheMaryTylerMooreShow''. Outside of her TV persona, Sue Ann was cruel and man-hungry, the antithesis of Rose. Rue, meanwhile, had played sweet but scatterbrained Vivian Harmon on ''Series/{{Maude}}'', as well as prissy spinster Aunt Fran on ''Series/MamasFamily''.
** Rue [=McClanahan=] had previously appeared in a famous episode of ''AllInTheFamily'' as the exhibitionist wife in a swinger couple whom Edith invites to the house after misunderstanding their personal ad.
** According to Rue, this was a major reason that Bea Arthur agreed to star; previously, she'd told Rue that she had no interest in doing "Maude and Vivian meet Sue Ann Nivens."
* RealitySubtext: In the episode "Sick and Tired", Dorothy is diagnosed with Chronic Fatigue Syndrome, from which condition creator Susan Harris also suffers.
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Chickens]]: The episode with the live chicken, Count Bessie, had to be rewritten slightly in regards to who was standing where during the scene, because Bea Arthur, despite being an animal lover, had a phobia about live chickens.
