Continuity mistake: In this episode, Blanche goes out with Stan, which results in the two of them becoming good friends who see each other often and hang out together. The only reason they end their friendship is because Dorothy got jealous, not for personal differences between them. Although Dorothy assumed the two have an affair, it turns out they were really just platonic friends who liked going out together. Still, in every episode afterwards, Blanche dislikes Stan again and treats him like an annoying person just like before, even though in the meantime she figured out how much fun he can be as a friend.
Continuity mistake: Whether Gladys Goldfine is alive or dead changes from episode to episode. For example in one episode, Sophia is mad at her because she doesn't take her out to a Tony Bennett concert and we see her apologizing to Sophia in the end, but in an earlier episode Salvatore's spirit told Sophia that Gladys has an affair with Charlemagne in heaven.
Continuity mistake: In the episode where Sophia loses her glasses, Dorothy answers the door and Sophia says "is this 6151 Richmond St?" In the episode where Dorothy has taken up smoking again and sets off the smoke alarm, Blanche and Rose rush into the kitchen, Blanche dials 9-1-1 and says "send a firetruck to 5161 Richmond, I'm on fire."
Character mistake: In her first appearance, Kirsten liked Dorothy, Sophia and Blanche and said that after her visit she now understands why Rose loves living with them. In her second appearance, she heavily dislikes the three women and states that she never understood why Rose preferred living with them over moving in with her.
Suggested correction: In her second appearance, Kirsten walks in while the women are laughing about something unrelated in the waiting room and her mother is in the hospital after a Heart Attack. Could it be possible that she's a bit upset, not thinking, and forgetting about what she said in her previous visit? In her first visit, she sees the positive, but subsequently she saw things she found questionable (she mentions things she sees like all of them getting into a car dressed strangely (it was for a play but she didn't know that)), and eventually her mother has a Heart Attack. She may have simply put two and two together and got five. It's a human characteristic, not a character mistake.
However, in her first appearance she specifically said at first she didn't get why Rose lives with other women but after having met the three she now understands why she's living with them. In the other episode she states she never got it in the first place.
Yes, We Have No Havanas - S4-E1
Continuity mistake: At Fidel's funeral, Sophia talks about him awakening feelings that she had not felt in 35 years. But earlier in the episode, Dorothy said that her father/Sophia's husband has been dead for 27 years. Also earlier, Sophia claimed to have showered with a man 22 years ago.
Revealing mistake: Dorothy brings out a pot of coffee and pours it into cups. When her friend Barbara is leaving, Dorothy is holding on to the "hot" coffee pot like it's not even hot. (00:07:50)
Continuity mistake: Blanche's attitude towards birthday parties changes throughout the show. Originally, she disliked them, but Rose changed her mind when she invited several men Blanche desired, as is seen in a flashback. In the same episode, the Golden Girls threw a surprise party for her which she was happy about. In a later episode, she hates birthday parties again (with Rose being baffled she doesn't like them), but is happy again at the end of the episode when Rose invites men to her party.
Plot hole: In the flashback, neither Dorothy and Stan nor Sophia and Salvatore own a TV yet. Still, Sophia knows exactly what shows each of the four like. It's unlikely Sophia regularly watched TV before as Dorothy believed her when she lied about thinking a TV is a waste of money.
Other mistake: Rose and Blanche are having dinner out on the patio with Rose's ex Thor. He says he has to use the restroom - the bathroom is on the other side of the house down the hall, but he's back in 20 seconds.
Other mistake: Rose says that she was "eventually" adopted by the Lindstroms. Rose has previously stated that she lived at the orphanage for eight years. While "eight years" could qualify as "eventually," Rose also says that the Lindstroms took the beef sticks that were left in the basket with her, and that the basket contained cheese and crackers, as well. None of those items have a shelf life of eight years.
The Engagement (a.k.a) Pilot - S1-E1
Other mistake: When Dorothy and Rose go back to Blanche's bedroom to ask her about her engagement to her BF Harry, they use the entrance that is normally used for the lanai. Possible set change.
Other mistake: Notice when Dorothy gets up to talk to the doctor. She's barefoot.
Revealing mistake: Blanche, Dorothy and Rose that went on the boat with the 3 guys were stranded on what appears to be a beach. However, the "beach sand" has a lot of bouncyness to it. Giving the look of foam padding of some sort with some fabric that looks like sand. The sand doesn't actually move either while they're walking on it. (00:16:11 - 00:18:40)
Revealing mistake: Throughout the entire series every time someone is cooking on the stove there's never any steam coming from the cookware. Also looking at the burners, it's an electric oven yet the burners are never orange indicating they never really "cook" food at all.
Character mistake: Sophia tells Dorothy that lying is breaking a commandment, to which Dorothy corrects her by telling her that it's not a commandment. Actually, not lying is in fact a commandment. The biblical quote is "Thou shalt not bear false witness against thy neighbor." Whether it's an error on the part of the writers or an intentional mistake for Dorothy, it's still a mistake. (00:12:15)
Revealing mistake: The "sand" on the beach of the supposedly lonely island Blanche, Rose, Dorothy and the three men stranded on is one solid cloth made of a rubber-like material. It wobbles and bends whenever a character's feet are on-screen.
Visible crew/equipment: At the very end of the scene at Sophia's new apartment, you can see a boom mic move above Dorothy's head.
Plot hole: It shouldn't matter if the neighborhood's got a petition. If the tree in question is on Mrs. Claxton's property then they wouldn't have a say in the city removing it.
Other mistake: There's a lot of talk about Pepe hurting his hands during his last boxing match. Unless there's something I'm missing, boxing gloves should provide adequate protection.
Other mistake: Rose tells a story about her mother having undergone plastic surgery to look like Raymond Massey back when she still lived in St. Olaf. However, we see her mother in an earlier episode and she looked nothing like him.
