An explorer in the Amazon suddenly finds himself surrounded by a hundred natives.
Panicking, he mumbled " Oh, GOD, I’m screwed."
The sky darkens, and a voice booms out
“No, you are not screwed. Pick up tht stone at your feet and slay the chief with it.”
The explorer pick up the stone and does just that.
He looks up from the chief’s lifeless body in time to see the natives angrily lift their spears.
Just then the voice booms out again: “OK, Now you’re screwed.”
