In the beginning there was darkness. And then the lights came on and standing there was Man, grinning stupidly. He had just finished taking out the trash when something popped into his very underdeveloped brain. It was a joke. Better than that, it was one that he had thought of himself. And it was funny! So he ran back to his cave dwelling and found Woman.
She was doing the crossword puzzle that came each morning on the Daily Tablet. Man was so excited that he made Woman stop and listen to his joke. It was a joke about three rocks, a big rock, a small rock, and a medium rock. Man picked up three rocks to illustrate. He had the big rock cradled in his right arm, the medium one in his left, and he was holding the small one in his hand. He made several points about the small rock, and then exchanged it with the medium rock and made several points about it. Woman had no idea where this was leading, but smiled patiently.
Now Man was working up to the punch line. He carefully worked the big rock to the front and began making several very animated points about it. Woman was a little uncomfortable because it didn't look as if it was going to be a very funny joke. Man was just about to give the punch line when some airborne pollen entered his nose and caused him to sneeze. As his chest expanded and contracted, the precariously balanced rocks he was holding became disheveled and the small rock fell out and landed directly on his left big toe. Man yelled out in pain and grabbed for his injured toe but in his haste the medium rock slipped out and landed on his right big toe. Man yelled out in pain again and tried to grabbed for his right toe. But Man could not hold the big rock, hold his toe, and stay in one spot so he began to hop around on one foot.
He hopped all around the cave dwelling, narrowly avoiding collisions with furniture, family heirlooms, and Woman. It then it occurred to man that a good idea would be to put the big rock down. He was just going to do this when he remembered that he hadn't yet given the punch line and that the big rock was essential to its delivery. His joke, he thought to himself, was so good, so funny, so important that it would be almost criminal to not finish it.
He mentioned this to Woman, who thought he should put down the rock. But Man was not to be stopped now. He began to hop back over to where woman was sitting. He was about to deliver the punch line when he bonked his head on a low-hanging piece of rock. Man grabbed for his head with both hands, dropping the big rock on his left foot. Man fell forward, trying in vain to stay upright. Woman jumped out of the way as Man gave into gravity and crashed-landed on the Daily Tablet, breaking it into several small pieces. Woman laughed like crazy.
