When you play the Game of Stones, you freak out or you die.
The Mountain completely sliced through the competition by taking first in three different events, according to Gawker, but the greatest highlight came when he completed a stone lifting challenge. After placing the final stone, the 6'9'' Icelander ripped off his shirt and went on to yell, "I am the future of strength as I am King of the Stones!"
You definitely have to see it. (No offense, Oberyn.)
