* 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}}''.
* TheCastShowoff: Bea Arthur got to sing in a few episodes. Not to mention Betty and Rue get to show off their dancing skills.
** Subverted with Rose's occasionally playing the piano; Betty White was actually unable to do so, so the crew had to use trick camera angles to cover her hands.
* CelebrityParadox: Shows up a few times:
** In an early episode, the girls are suffering from a flu and argue over which soap opera they should watch; Blanche wants to see ''AnotherWorld.'' Rue [=McLanahan=] appeared on that particular soap in her younger years.
** In "Ladies of the Evening," Rose lists off some of the celebrities that will be attending the premiere of Burt Reynolds's new movie. Charles Nelson Reilly is on the list; Betty White made several appearances on ''The Match Game'' with Reilly.
** Sylvester Stallone clearly exists in the Girls' universe, as Rose mentions ''RockyIV'' in one episode. Stallone appeared with Estelle Getty, who played Sophia, in the infamous flop ''Stop! Or My Mom Will Shoot!''
** In two different episodes, Dorothy, played by Bea Arthur, sings a few bars of songs from ''FiddlerOnTheRoof''. Guess who played Yente the Matchmaker in the original Broadway production?
* DawsonCasting: Inverted with Sophia. Estelle Getty 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.
* HarpoDoesSomethingFunny: In a minor example, Betty White improvised the various [[AsLongAsItSoundsForeign "Scandinavian"]] words her character uses.
* 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, [[TheGeorgeLopezShow Valente Rodriguez]], 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. Dorothy finally gets her happy ending by marrying [[TheNakedGun Lieutenant Frank Drebin]], Series/PoliceSquad
** Don't forget [[SweeneyToddTheDemonBarberOfFleetStreet Sweeney Todd himself]] showing up to play Foxy Loxy in a grade school production in "Henny Penny: Straight, No Chaser." Humorously, [[ActorAllusion Foxy eats Henny Penny, Goosey Loosey, and Turkey Lurkey in the show]].
** Also applies behind the scenes as well.

* RealLife/MeanCharacterNiceActor: Bea Arthur said that Herb Edelman was nothing like Stan (the character he portrayed in the series).
* 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.
** Interestingly enough, Herb Edelman, Monte Markham, Sheree North, Scott Jacoby, Lynnie Green, Sid Melton and Nancy Walker were (as Stanley Zbornak, Clayton Hollingsworth, Virginia Hollingsworth, David Zbornak, Young Dorothy Zbornak, Sal Petrillo, and Sophia's sister Angela) the only recurring family members to appear throughout the series without changing actors.
* [[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.
* ThrowItIn: A particularly sweet version occurs in "Valentine's Day." Throughout the episode, Sophia claims that she has a date with famed Latin singer Julio Iglesias; when the girls leave for their own dates, Julio himself shows up at the back door. The producers of the show wanted Iglesias to sing a song, but when it came time to film, he felt he was not able to do so and refused, leaving them panicked. However, Estelle Getty, who played Sophia, suffered from stage fright of her own and promised to handle the situation...by singing to Iglesias herself. The plan worked, and the episode ends with Sophia and Julio singing "Begin the Beguine" together as they leave the house.
** Getty provided another example from her final audition. She decided to wear age-appropriate clothing, and found various thrift store items--including a purse, which she felt was key to the character, as a woman of Sophia's age would carry all of her important medications and items in her bag (indeed, Sophia almost always had her purse with her during the show, including moments when she came into the kitchen in the middle of the night). The props department ended up using the purse Getty chose on the show, and even had a spare made.
* UnderAgeCasting: Estelle Getty was 62 when she started playing Sophia, the 80-year-old mother of Dorothy, [[PlayingGertrude despite being a year younger than her onscreen daughter Bea Arthur]].
* [[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.
