We certainly wouldn't like to get on the wrong side of Gregor Clegane, or The Mountain as he is nicknamed in Game of Thrones. One airline was certainly not afraid to stand up to him though, all be it from behind the safety of social media.

Actor Hafþór J Björnsson is Iceland's strongest man and while travelling on his country's national airline recently, he sent out a Tweet complaining about the size of the airlines seats. Well he is built like brick sh*thouse in fairness.

 

 

The airline wasted no time in getting back to him though and had this clap-on-the-back comeback for him.

 

The actor retweeted it from his account so was all in good humour, well unless he decides to go all 'Mountain' on their asses when he returns to his homeland...
