Starring: Tom Selleck, Roger E. Mosley, John Hillerman, Larry Manetti
Don't Eat the Snow in Hawaii - S1-E1
Plot hole: The clock at customs signals it is 9:05 AM when Lt. Dan Cook arrives at Hickam. Magnum narrowly misses him. Then he goes back home...and it is night. There is no reason why Magnum would have spent the whole day out of the house, especially never checking on his fraternal buddy he was supposed to chaperone to begin with.

Continuity mistake: When Magnum drops the ring out of the envelope, nothing is near it as it's shaking. In the close up shot, it's next to keys. (00:44:20)
Mac: Time has little to do with infinity and jelly donuts.
Trivia: Tom Selleck is the only actor to appear in every episode of the show.
