Audio problem: When Samantha reveals her spanx, there is the clear voice of a man (crew) saying something inaudible. (00:11:30)
Continuity mistake: When Carrie and Miranda walk through the park with the boys there's a man in a blue and yellow jacket behind who suddenly disappears. (00:15:20)
Continuity mistake: While Carrie strolls through Central Park with friends there's a living statue version of Lady Liberty behind, standing and talking to people. A shot later the people are gone and the statue is seating on a bench.
Continuity mistake: When Carrie sits by the fountain the whole scene swaps between close-ups of her or the boy with a very sunny light, and wide angles of both with a cloudier grey atmosphere.
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.
