I really enjoy the TV show Monk, but they constantly make serious errors just to get their stories to work. Tonight's episode had a murder take place on a U.S. Navy submarine. I am almost positive that the murder weapon was a P-38. Okay, you say, maybe the murderer just snuck that sidearm on board so he could commit murder with it.
No. Because when Monk asked another sailor for his sidearm, he handed him another P-38.
Oh, and if you're about to ask if anyone actually cleared the weapon before decisively stating, "it isn't loaded," then surely you must know that you're about to ask a silly question.
P.S. The most egregious error in the show that I ever saw was when Monk's dad visited. I had to spend the last 15 minutes of the show explaining in minute detail why what was happening to his 18-wheeler was absolutely impossible and could not ever happen under any circumstances whatsoever.
