Bad things happen when normal-sized humans challenge Gregor Clegane to a fight -- ask Oberyn Martell. Thankfully, Interim UFC Featherweight Champion Conor McGregor didn't have his skull crushed like The Viper. Instead, he almost cut down a mountain.

You can tell both people are going easy on each other -- which is probably for the best. McGregor can literally run circles around Hafthor Bjornsson, who plays "The Mountain" on Game of Thrones. Let's not undersell what Bjornsson can do. He's one of the strongest men on the planet, he couldn't probably rip someone's arms off. We're just glad this ended in smiles, rather than screaming.
