Continuity: As with any long-running show there are many inconsistencies between episodes. Characters' life histories, their birthdays and ages are reported differently from time to time as the writers invent new stuff for them that wasn't thought of when the series began. "Facts" are altered to fit the jokes, and a good deal of leeway is allowed.
Continuity: The layout of the house changes between the pilot episode and the rest of the series.
Revealing mistakes: The layout of the house is entirely illogical. Not only does it not match the exterior shown, but the lanai is not in the back of the house, it's on the side of the front. The back hallway of the kitchen does not lead to the garage, it runs into the hallway to the bedrooms. The hallway to the bedrooms exists by itself, as either side of it leads to the kitchen or the backyard. The door on the side of the garage is on the wrong wall according to the layout of the kitchen, and the exterior of the house.
Continuity: When the girls refer to the house, the address is quoted as either 5161 or 6151 Richmond Street.
Factual errors: In the episode where a robber breaks into the girl's house, Rose gets paranoid and buys a gun. When she returns home, she said she learned how to shoot the gun in the "basement of the store". Basements are not allowed in Miami, Florida.
Continuity: In several episodes, Blanche reveals that her middle name is Elizabeth. But on the episode where her old nanny comes to visit, her nanny calls her "Blanche Marie Hollingsworth!"
Continuity: The front porch shown in various episodes does not match the picture of the house shown at the beginning of each episode.
Revealing mistakes: In the first episode that Michael appears, Dorothy says that he is 29, but later when he is to marry Lorraine, he is 23 and she is 44. Then when he comes a third time, he doesn't mention his child at all when she kicks him out of the house.
Miscellaneous: Dorothy says she was just a child when Sophia's mother dies.. but during the Mother's Day episode Sophia tells a story of when her mother came to live with her and Sal and Dorothy was an adult in it.
Revealing mistakes: The background set with two elevator doors is used as the backdrop for numerous interiors: the museum where Blanche works, the counseling center where Rose works, and the city hospital to name three. Also, the museum where Blanche works was used as a psychiatrist's waiting room.
Continuity: Depending on the episode, Dorothy either had no date for the prom and got pregnant by Stan, went to the prom with Stan and then got pregnant, or had another date to the prom who didn't show up and got pregnant by Stan. (Any way you look at it, though, Dorothy got pregnant by Stan.)
Continuity: Depending on the episode, the police called Blanche to inform her that her husband was killed in a car accident, or her husband died from a coma brought on by injuries from a car accident.
Plot holes: Golden Girls starts off by Sofia having a sister named Angela. During a conversation she states that Sofia and her are the only two relatives of the old family left, and that everyone else is dead. She fades away and then an character named Angelo comes in and you find out that he is Sofia brother, who should then should be dead according to Angela.
Continuity: In the episode dealing with Rose's drug addiction, she jokingly states that this was the anniversary of her cat "Fluffy"'s death, and Dorothy reminds her that she never owned a cat because she was allergic to them. However, in at least one other episode, Rose spoke of having a cat. In addition, she also stated his name was "Lingstrom" rather than Fluffy.
Continuity: In regards to the show in which Rose is fighting her addiction to pain pills and how she is allergic to cats, in one show where Blanche is reminiscing about how she first met Rose, Rose had a cat, Mr. Peepers, which she offered to a little boy to keep when Blanche later said that it showed her that Rose had character.
