An atheist

An atheist was seated next to a little girl on an airplane and he turned to her and said, "Do you want to talk? Flights go quicker if you strike up a conversation with your fellow passenger."

The little girl, who had just started to read her book, replied to the total stranger, "What would you want to talk about?"

"Oh, I don't know," said the atheist. "How about why there is no God, or no Heaven or Hell, or no life after death?" as he smiled smugly.
...
"Okay," she said. "Those could be interesting topics but let me ask you a question first. A horse, a cow, and a deer all eat the same stuff - grass. Yet a deer excretes little pellets, while a cow turns out a flat patty, but a horse produces clumps. Why do you suppose that is?"

The atheist, visibly surprised by the little girl's intelligence, thinks about it and says, "Hmm, I have no idea." To which the little girl replies, "Do you really feel qualified to discuss God, Heaven and Hell, or life after death, when you don't know shit?"

And then she went back to reading her book.

Life Explained

On the first day God created the cow. God said, "You must go to the field with the farmer all day long and suffer under the sun, have calves and give milk to support the farmer. I will give you a life span of sixty years."
The cow said, "That's kind of a tough life you want me to live for sixty years. Let me have twenty and I'll give back the other forty." And God agreed.

... On the second day God created the dog. God said, "Sit all day by the door of your house and bark at anyone who comes in or walks past. I will give you a life span of twenty years."

The dog said, "That's too long to be barking. Give me ten years and I'll give you back the other ten." So God agreed.

On the third day God created the monkey. God said, "Entertain people, do monkey tricks, make them laugh. I'll give you a twenty-year life span."

The monkey said, "How boring, monkey tricks for twenty years? I don't think so. Dog gave you back ten, so that's what I'll do too, okay?" And God agreed again.

On the forth day God created man. God said, "Eat, sleep, play, have sex, enjoy. Do nothing, just enjoy, enjoy. I'll give you twenty years."

Man said, "What? Only twenty years! No way, man. Tell you what, I'll take my twenty, and the forty the cow gave back, and the ten the dog gave back and the ten the monkey gave back, that makes eighty, okay?"

"Okay," said God, "You've got a deal."

So that is why the first twenty years we eat, sleep, play, have sex, enjoy, and do nothing; for the next forty years we slave in the sun to support our family; for the next ten years we do monkey tricks to entertain the grandchildren; and for the last ten years we sit on the front porch and bark at everyone.

Life has now been explained.
