Character mistake: Bickering with his pretend wife after risking his neck with the falling crates, Magnums says "we can stop playing house, I can go back to being a private detective, which is exactly what I should have been in the first place." Magnum has a verbal tic during the series and he fiercely corrects everyone when they call him a private eye, or detective, as he goes only by "investigator" (the I in P.I, after all). He's using the wrong word here. (00:22:35)
