Fighting Instructor Gets Completely Shown Up in the Most Unexpected Way

I'm calling FAKE on this video for a few reasons:

1. The main fighter focused on in the video turns around before anything happens in the background to watch the "fight."
2. The "fighter" that gets knocked through the wall, stands there just moments before getting hit, as if he's expecting it, without putting his hands up to guard his face or abdomen from any oncoming punch.
3. The VERY punch the guy is talking about is demonstrated in the background just seconds later.

FAKE! What do you think?
