Michael Sam -- Destroys TMZ Camera Guy ... With Epic 'Game Of Thrones' Ruse

Michael Sam just dominated a TMZ photog at LAX like he was The Mountain ... and we were Oberyn Martell ... and it's pretty damn hilarious.

Here's how it went down ... One of our crack camera guys got the newly engaged Sam to not only tell us when and where he's getting married ... but who he's inviting and where he's registered.

Awesome, right?

Now for the twist ... He's getting married in Westeros with Tyrion and Tywin Lannister -- AND Daenerys Targaryen (good luck with those three) -- and he's registered at King's Landing.

Yeah, it's Red Wedding-level deception.

Here's the thing ... most of you probably got the fact that those are all references to the HBO show "Game Of Thrones" -- but the one dude who didn't was our camera guy.
