Hot child in the city - S3-E15
Revealing mistake: When Carrie is scooting through New York, there are literally crowds of people gathering together watching the filming and staring at Carrie and the camera. There's even a big group standing in the middle of the road despite the traffic with a cop in front controlling the situation.
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.
