I have a book about the series and there's a cute bit of dialogue that didn't make it into an episode. They censored it. In the hospital scene when Rob picks up Laura and the baby, he doesn't want her to carry Ritchie. I think he asks her if she is able to do it. Laura's original reply was "I carried him for nine months. I think I can carry him out of the building."
Can you believe they censored that bit of dialogue? That was hardly offensive. Sometimes sixties TV went too far to censor things.
