Plot hole: Magnum and Rick manage to switch Yuri with Fillipovitch through sheer magic; they base their infiltration on a little boat barely big enough to contain the two of them, with no room for them to hide the uncooperative Russian, plus we see most of their movements including them climbing up. It's simply a 'shocking reveal', but it's not setup in any believable way.

Revealing mistake: One of the party guests opens the door of the fridge and you can see behind the set instead of looking into the fridge. (00:32:40)
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)
