There Goes the Bride (1) - S6-E16
Continuity mistake: As the show begins, an outside shot of the house shows that it is night. Then it cuts to the scene of Blanche and Sophia playing Chess in the kitchen - when Blanche is complaining about Sophia's "do-overs" you can see outside the kitchen window and it is daytime. After Rose walks in about 30 seconds later, you can see that it is night again.
Continuity mistake: Napkins, plates, etc. disappear from the table as Blanche is talking to Dorothy. (00:03:15 - 00:03:55)
Journey to the Center of Attention - S7-E19
Continuity mistake: In the first scene of the show, Dorothy has a bowl of popcorn on her lap. The amount of popcorn changes between shots. At one point it's overflowing, and at another it's about half full.
Continuity mistake: Blanche says she can't go to the Sinatra concert because her final exam is that night. In the first classroom scene, the chalkboard says that the final exam is in four weeks. But before Blanche gets home and tells the girls that her teacher wants her to sleep with him, Dorothy says the concert is in two weeks. It is the same day, since Blanche is wearing the same outfit and she wouldn't wait two weeks to tell the girls about her teacher.
Continuity mistake: When the girls are sitting around the campfire, the amount of burned wood changes from shot to shot. First it's partially scorched, then mostly scorched then partially scorched again.
Big Daddy's Little Lady - S2-E6
Continuity mistake: Dorothy takes a cheesecake out of the fridge and it's halfway gone. When she gets to the table, the cheesecake changes and has not had a piece cut out of it. When she sets it on the table, it is halfway gone again.
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: When the women are sitting at the table outside, Lily insists on pouring everyone's lemonade. She is shown pouring the first 2 cups, then in the very next shot the remaining empty cups are gone from the tray and everyone has their cup of lemonade.
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.
If At Last You Do Succeed - S6-E3
Continuity mistake: In the scene where Stan stops by the house to have Dorothy help him tie the bow tie of his tuxedo, the undone tie is hung around his neck. After Dorothy finishes tying the bow tie and Stan proceeds to leave, she stops him to tell him to return in an hour. He excitedly turns around towards her, at which point we can see that the bow tie is now a clip-on. (00:18:55 - 00:20:55)
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: When Blanche returns from a date with Ted (Stan's brother) she puts her pocketbook on the back of the kitchen chair then sits down. In a wide shot of the girls sitting at the table she still has the pocketbook on her shoulder/arm.
Continuity mistake: At Big Daddy's (Blanche's father) funeral/passing, Blanche shows Dorothy around her childhood home but it was revealed in season 1 episode 24 that Big Daddy had sold the property to pay for a music tour and to escape the constant reminder of his late wife, the house was named Twin oaks.
Continuity mistake: When the girls are singing to the baby, the blankets keep disappearing and reappearing on the baby carriage.
Brother, Can You Spare That Jacket? - S4-E8
Continuity mistake: At the end of the episode, the girls regroup after looking for the winning scratch-off ticket and Blanche says she found it. At that moment, she is not holding her purse, however in the very next shot, after the priest enters the room, she's suddenly holding her purse again without the girls ever having moved from their spots.
Continuity mistake: When Dorothy, Blanche, and Sophia are sitting in the reception area arguing with Kirsten, Sophia sits forward and says she loves Rose as if she was one of her own. When she sits forward, you can see the beads on her purse handle are strung tightly. When she leans back in her seat, you can see big spaces between beads, as if some have been taken off.
Job Hunting - S1-E22
Continuity mistake: In season 1 episode 12, the wallpaper and wall decorations are changed in the kitchen but in this episode they revert back to the original.
Suggested correction: That's because the episodes were aired out order than when they were produced. This episode was the second episode produced (production code "002") whereas episode 12 was the 14th episode produced.
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."
