In this episode Jerry Orbach is talking to his partner and mentions how he is very cynical about marriage, and how couples split up. His partner said my grandparents HAVE been married for 50 yrs. I think the line was written my grandparents WERE married for 50 yrs. No one caught it.. If his grandparents were married for 50 yrs. and he appears to be in his 40s or possibly late 30s that would make them approx. 9 or 10 yrs. older. Not at all possible.
