A shipwreck survivor washes up on the on the beach of an island and is immediately surrounded by a group of native warriors.
“I’m done for!” he cries in despair.
“No you are NOT!” - comes a booming voice from all around him. “Listen carefully son, and do exactly what I say. Grab the spear from the man on your left use it to stab their chief in the heart.”
The man grabbed the spear and in a strength born of panic he stabbed the chief, who collapses, dead.
The remainder of the tribe stare at him in disbelief. You could hear a pin drop a 100 feet away.
“Now what???” - the man asked the voice.
And the booming voice answers: “NOW, my son, you’re done for.”
