The caveman stumbled out of his cave and stubbed his toe on a rock.“Ow!” he exclaimed.
That became the first word for rock.
When he told his mate he had met an ow, she decided he must have been chewing loco weed.
But he argued that it was an ow for creatures he had slain, that he had seen it since he was born, but didn’t know its name.
Then he hit her foot with the rock.
"Ow!’ she exclaimed.
"See,"he said. “Enough ows and you die.”
So began philosophy and religion.
