In the year 2019, there are two types of boxing knockouts: regular knockouts and instant memes.
This is the latter.
There's not much to say here other than the person doing the punching is Cassius Chaney. The person being punched is Joel Caudle.
The video doesn't really do it justice; imagine sitting ringside and seeing this massive human being barreling toward you headfirst:
First, shoutout to Caudle for having the toughness to make his way back into the ring. If you knocked me clear out of the boxing ring, you'd need to pick me up with a human spatula because I'd never want to move out of pure embarrassment.
Second of all, that face-plant topple is the stuff that memes are made of. Caudle should be thankful for the person in the front row who attempted to help him brace his fall. Otherwise, a funny moment could have turned scary in the blink of an eye.
