Good info, Harvey.
If you meant the whole of her dialogue, then that's that. The anecdote I saw was probably that she surprised Nimoy with her second bit: "No, you have an answer: I'm an illogical woman..." and she spins this unscripted banter and winds up at a full moon on Vulcan. And Nimoy supposedly played along and ad libbed that Vulcan has no moon.
But if that was her doing, then she was discouraged from getting playful as the series went on. They didn't want risk
Star Trek turning into
Julia. Shatner and Nimoy would both have been threatened by that. The example of
Jonathan Harris on
Lost in Space looms large.
The "no moon" line gives us a problem when TMP comes along, but that's the movie era for you. Continuity was not a priority.
