In the beginning...

there was man. There was woman. There was nature and cute little critters that man could kill and woman could cook. Life was good. Man and woman killed, cooked and procreated. They procreated a lot. They made more men and women who went forth killing, cooking and procreating. They were happy.

One day man tried to procreate with woman after a successful kill and cookout. Woman was tired from the cooking, complained that her back hurt from kneeling and bending to cook. Man thought and thought. Procreating face to face was invented by necessity. Life was good.

Soon after the advent of what we now know as the "missionary position" man attempted to procreate with woman. In this position womans mouth was near mans ear. She talked. Man, to his amazement, learned that woman was unhappy. Her back hurt from bending over to skin and butcher the animals which he killed. Procreating was not as much fun now.

Man went out with other men to hunt. They found fermented berries and sat under a shade tree eating berries and napping. That night, during prcreation, woman talked even more. Man fell asleep.

The next morning woman went out gather wood with other women. They talked, a lot. There was no procreating by anyone that night. Or the next.Or the night after that.

One morning, after a night of drinking fermented berry juice and no procreating, man took his stone ax out to the woods. He cut down a huge tree. He didn't need to cut down the tree, but he needed to release some pent up "energy". He finally wandered deeper into the woods and got a grip on himself.

He returned to the cave to find woman smiling and happy. She thanked him for cutting down the tree. She used the stump for a table and tonight, her back did not hurt. They procreated.

Soon after, all the other men in the tribe cut down trees for their women and all were happily procreating. Soon there were stumps everywhere with women happily working away. Then it rained.

They retreated to the cave and woman began to complain as she knelt on the ground preparing dinner. Man could not drink his fermented berry juice in peace. He went out in the rain, climbing over and through the fallen trees to sit gazing at the field of stumps. He sat and thought. He saw how an over-turned birds nest kept the ground beneath it dry. He took the nest apart. That night there was no procreating.

Early the next morning he began building a huge upside down birds nest over womans stump. it was warm and dry and they procreated. A lot. The other men heard the procreation. The other women heard the prcreation. After the procreation woman proclaimed loudly how warm and dry the upside birds nest was.

In the ages that followed men rose early to build upside down bird nests. Sometimes we even get to procreate if woman likes the birds nest.
