Here is one ridiculous one from a single TV series, Barnaby Jones.
The early years were notorious for being very cliched. First, there were always two deaths. The one right away, and another about at the halfway point. Even sometimes the first death was accidental, would have been involuntary manslaughter or the person just fell, punishment probably limited, the perp still decides they have to cover it up and go ahead and murder the second person.
Then, the endings. Ugh. Every single ending, the perp is trying to flee, takes a single shot at Barnaby, misses, then Barnaby shoots them in the arm or hand. Every single time. Well, not every single time, David Wayne once shot twice at Barnaby with a shotgun, and I think Barnaby killed him. A special exception for sweeps I guess. Also, if the perp was a woman this was not allowed to happen. Women didn’t get to shoot at Barnaby or get shot. They either had to have a male accomplice that took the shot, or Barnaby talked them out of it or grabbed them or it ended some other way. Even if they had shot and killed their victims.
Later on they did get better writers and got away from such cliched scripts. But there were over 100 episodes that ended the same way.
