The Mountain from Game of Thrones lost to this guy in arm wrestling

The Mountain can survive a fight to the death, but Hafthor Bjornsson can't beat this arm wrestling champion.

The Mountain can survive an on-screen fight to the death, but Hafthor Bjornsson can't beat this arm wrestling champion.

The Game of Thrones star—who stands 6'9," weighs 419 pounds and is Europe's strongest man—engaged in an arm-wrestling bout with world champion arm wrestler Devon Larratt, no slouch himself at 6'5," 225, but still much, much smaller than dude. 

Watch their match below and see what you think. Larratt engages in some... dubious body-leveraging tactics, but clearly wins.

SPOILER ALERT:

Guess somebody had to avenge Oberyn.
