Don't look him in the eye...

I'm guessing the man attached to this hand has seen his share of knockdown, drag-out brawls. There might've even been a time, as recent as this post I imagine, when he walked through raining gunfire without flinching just to finish the shot of whiskey he left on a bar... or stared down a man holding a flame thrower, knowing the man with the flame thrower wouldn't take the chance that the ball of fire he set forth wouldn't kill before he could be disarmed and killed himself... just guessing. There's also a pretty good chance that each of those skull rings represent a backyard cage fight victory where the opponent died. Just saying...
