Watch: Game of Thrones' The Mountain gets destroyed by arm-wrestling champ
Strength isn't everything.
You'd think that Hafthor Bjornsson, the World's Strongest Man runner-up best known for his role as The Mountain in television series Game Of Thrones, would be a fairly handy arm-wrestler.
But while the Icelandic giant would undoubtedly be an immoveable opponent for most, he met his match when he came up against professional arm-wrestling champion Devon Larratt.
Larratt, who weighs nearly 90kg less than Bjornsson, took on the strongman and beat him with surprising ease.
