I’m not really sure what is going here. From the looks of it, this is a class on MMA and this instructor is demonstrating some type of punch on a student.

This student clearly did not know he was actually supposed to defend himself because he got knocked the f**k out.

By the reactions of the students, this must be pretty routine seeing as they all just laugh when this dude drops like a sack of potatoes.
