When Picard meets Perrin on the Enterprise, he gives her a cup of mint tea that is filled up to a marked line on the mug.
Crusher tells Picard that, if he wants his prosthesis to fit, he has to trust his tailor. A tailor fits and modifies clothing, not prostheses. A more appropriate term would be "prosthetist." However, Dr. Crusher is using a metaphor as a jest, not being factual.
When Dokachin accesses the Enterprise's computer and downloads the registry of the Vulcan ship they were looking for, he says the Stardate of arrival was "41344", although the computer display clearly shows "41334".
