I actually noticed this when I watched the video the first time. I honestly wasn't sure if that was the same guy as the earlier pic as of "Sam" and I was thinking, I'll just leave it alone for now. Like how can Chrissy just fucking inadvertently screw up any more in his videos. The guy wanted to be anonymouse and he catches his reflection in a plate.

Elmo's view of him makes it pretty clear it is in fact "Sam (Sure, sure, you guys go, I'll just take care of your wife) the Man".
