An explorer in the deepest Amazon suddenly finds himself surrounded by a bloodthirsty group of natives. Upon surveying the situation, he prays quietly to himself, "Oh God, I'm screwed."
The sky darkens and a voice booms out, "No, you are NOT screwed! Pick up that stone at your feet and bash in the head of the Chief standing in front of you."
So with the stone he bashes the life out of the chief. He stands above the lifeless body, breathing heavily and looking at 100 angry natives...
The voice booms out again, "Okay....NOW you're screwed."
