Continuity mistake: It is known that Dorothy married Stan because she was pregnant and they were married for 38 years. However Michael is not 38 - his age is stated as either 23 or 30 in different episodes, a mistake in itself - and in the 2 episodes her daughter is in, she doesn't look to be anywhere near 38 either.
Continuity mistake: In one episode, Rose talks about being valedictorian of her high school class in St. Olaf. In another episode, Rose goes to night school (where Dorothy is her teacher) in order to get her GED because she never graduated from high school. While talking to rose about the class Dorothy states the class is for people who didn't get a diploma. Additionally, in the episode "Whose face is this, anyway" Rose mentions that she was in a sorority called the "Alpha Yams"; when the girls look at her strangely, Rose states "It was an agricultural college." She could not have gone to college without a high school diploma.
Continuity mistake: In series 3 Dorothy's son Michael, who is engaged to a woman 21 years older than he, is supposed to be 23. In Series 2, when Michael sleeps with Rose's daughter, Dorothy mentions that he is 29 years old.
Continuity mistake: Angela says that she and Sophia are the only ones left living in the family, but in later episodes their brother Angelo shows up.
Continuity mistake: Throughout the show, Rose implies through numerous stories that everyone in St. Olaf, explicitly including close family members, is just as dumb and weird as Rose herself. However, most of Rose's relatives we meet are perfectly normal people, including her adoptive mother, both of her daughters that we get to see, her biological father and her blind sister. During a dream sequence, her adoptive father appears and he doesn't seem to be unintelligent either, giving her good advice. Only her cousin Sven fits her description by being arguably even dumber than her.
Continuity mistake: In the episode when Dorothy is trying out for Jeopardy, she is sitting on the couch studying, When Sophia sits down to talk to her Dorothy is looking at a page with just words, It cuts to Sophia and then to Dorothy and the page now has pictures on it. You can still see the corner of the book when the frame is on Sophia and you can see that Dorothy did not turn the page.
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."
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.
