Character mistake: At the end of the episode, Magnum says "You know what they say about samurai swords - you unsheathe 'em, you gotta draw blood!", but throughout the episode, Tozan drew his sword on Magnum and the villain and no blood has been drawn - in case of Magnum, there was no intention of it either.
Higgins: How fiendishly deceptive of you, Magnum. I could have sworn I was hearing the emasculation of a large rodent. To my great surprise, I see the sounds are emanating from what I thought was a harmless musical instrument. Magnum: Cute Higgins, real cute. Higgins: Why Magnum? Why do this terrible thing? Magnum: Higgins, I'll have you know I used to be very good. I was the second best sax player in my High School band! Higgins: Well, how many sax players were there?! Magnum: ...Anyway. I just saw this in a pawn shop window and thought I'd like to try and get my chops back. Higgins: May I suggest that your "chops" are irretrievable. Magnum: Higgins, did you come here just to abuse me!?(00:05:25)
Trivia: In some episodes during season 8, Magnum wears Polo Ralph Lauren safari animal print shirts in both tan and white. At the time, those shirts cost nearly $400 each.
