UFC fighter Conor McGregor is a professional. He can spar with the best of 'em. But when it comes to taking on a 6'9" 400lb man, all of that kind of goes out the window, to be honest. Who am I referring to? None other than Gregor Clegane a.k.a. 'The Mountain' himself, from Game of Thrones.
His real name is Hafþór Júlíus Björnsson, and he's actually pretty spry for someone of his stature. You've got to see the video yourself to understand how amazing this truly is.
Of course, The Mountain is most famous because of his fight with The Viper on 'Game of Thrones'
While this sparring battle probably wasn't as epic as the video above, it did have some similarities...
I'm pretty sure this hurt, too:
He had a clear size advantage, but McGregor is no scrub. I'm just glad that I don't ever have to get in the arena with either of these dudes. I would get wrecked and so would you.
