Ah, with a thread title like this one, its like saying "Winter is Coming" in The Game of Thrones.
And so... fade in from white... we see a Neanderthal cast wearing animal hides in the cover of darkness, they are all drunk, yelling and howling at the moon, with fires lighted throughout the scene, chainsaws scattered all around them, and wood chippers parked about. The women are scantly clad in animal furs, and dogs are howling with the men at the moon. Slowly the drums begin to beat and they as increase in tempo the women begin to dance with arms laced in a weaving thread among them. A high priest emerges from off set and climbs to a platform. He turns and announces in a loud booming voice over the drunken crowd:
Summon the oil Demons! Let the OIL WARS RECOMMENCE!
And with that they all take a drink of ale or cider from two large caldrons. They all raise their wooden mugs and chant:
My oil is better than your oil! My oil is better than your oil! My oil is better than your oil!
And with that they fall into a huge fight that lasts for hours, then dragging on for days, then weeks, and then many months, until they are all dead from exhaustion.
And so the Neanderthals became extinct.
