Not sure how their paths crossed, but mixed martial artist Conor McGregor and Icelandic strongman Hafthór Björnsson have a video out in which they’re fighting one another.

Thankfully, Björnsson is not as brutal as his Gregor “The Mountain” Clegane character in Game of Thrones.

It’s tense to watch however, I keep thinking “don’t piss him off!” McGregor every time he lands a hit.

Björnsson seems like such a cool-headed guy, though.

In fact, the video becomes quite cute…like a massive bear toying with a tiny kitten, checking its pain threshold every once in a while when he can catch it.

Björnsson is a hugely accomplished strongman.

In case you missed it earlier in the year here he is breaking a 1,000 year-old Viking strength record (carrying a 32-foot, 1,433 pound log).

No big deal.
