The Golden Girls (1985) - 4 mistakes in whole show

Continuity: In series 3 Dorothy's son Michael, who is engaged to a woman 20 years older than he, is supposed to be 22. In Series 2, when Michael sleeps with Rose's daughter, Dorothy mentions that he is 29 years old.

Continuity: In the episode "Bring Up Baby". Blanche says she has had 4 children, but she has never owned a Mercedes. She offers one of her three sons (named Biff, Doug and Skippy)to Dorothy in order to let her keep the car. In other episodes she mentions daughters Rebecca and Janet frequently, and in the "To Catch a Neighbor" episode she mentions a son, Matthew, who is a CPA. That's at least six children by my count.

Continuity: 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.

Plot hole: Blanche's story about when her husband died, changes through out the series. At one point she was getting a pedicure when he was killed. And then she told a story about how she tripped over one of his shoes when she got the call that he was in a car accident and had died. And in another story she said that he had been in a coma and died.
