Continuity mistake: When Carrie is startled by the squirrel and tosses the pie crust onto the counter, the camera cuts to her clasping her legs where she burnt them. In the next shot of the counter the pie crust has vanished; then in the next shot of it, the crust has returned. Also, the tray and tea towels change positions.

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.
