WATCH: Jose Aldo's cornermen reacting to the knockout is something you'll never forget
It's wrong to laugh so just don't.
But the reaction in Jose Aldo's corner as Conor McGregor uncorked his left hand is a little bit spectacular.
Marlon Sandro, Aldo's main training partner, absolutely lost it when he saw the now-former UFC featherweight champion crumble in the first exchange.
We didn't think that it was possible to cram every human emotion into one six-second Vine but dammit, it was managed.
