Revealing mistake: When Carrie is watching TV in her apartment, she uses the remote to click off the TV after SNL is over. There is a close-up of the TV screen, reflecting the room in front of it. You can see a round table with a lot of stuff on it, the windows/curtains and desk, and what appears to be a square ottoman of some kind. But Carrie is nowhere in sight, there is just a blank wall reflected where her image should have been. She is directly facing her TV, as shown from the angle of her perspective as she clicks it off. We should be able to see her somewhere within the television reflection, but she isn't there. (00:20:10)
Continuity mistake: When Carrie and Steve are sitting on his front steps discussing Aiden, Carrie is looking forward as Steve says "He lost his ability to open up and trust women." At that moment; Carrie turns her face towards Steve to her left, and keeps it there as she is appalled. But the very next shot; Carrie is suddenly facing forward again, and then starts turning her head left towards Steve for a second time. But in the next shot; she is already facing Steve, from the first time she reacted to what he said. It's clear that she had never actually moved her head after the first time. (00:25:30)
Continuity mistake: At the market, Stanford's hands are crossed by his tummy, but a shot later they're crossed behind his back. (00:25:46)
Continuity mistake: Bunny grabs the telegram from the lower part. A shot later she is grabbing it from the side.
Continuity mistake: When Sam wants to return the neck massager, it has cables tangled all around or not, depending on the shot.
Continuity mistake: Miranda is in the toilet, her purple towel and scarf lying on the sink. When the shot changes the scarf is missing. (00:10:39 - 00:11:00)
Continuity mistake: When Miranda's neighbour is scolding her, the neighbour's head is tilted sideways. Then she straightens it up but from the opposite angle it remains tilted for several seconds.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
