Watch UFC Fighter Conor McGregor Fight the Mountain From Game of Thrones

It’s badass vs. badass.

In one corner we have Conor McGregor, #1 ranked feathweight UFC fighter and notorious trash-talker, who comes in at 5’8” and 145 pounds. In the other, we have Hafþór Júlíus Björnsson (don’t ask me how to pronounce that), Icelandic strongman who plays the Mountain on Game of Thrones, broke a 1,000-year-old Viking weightlifting record, and can down seven whole chickens in one sitting. Oh, and he’s also 6’9” and 419 pounds. For some reason, McGregor agreed to fight Björnsson (or the dude lost a bet). Watch how the fight went down below.
