On the first day, God created the dog and said, "Sit all day by the door of your house and bark at anyone who comes in or walks past. For this, I will give you a life span of twenty years."
The dog said, "That's a long time to be barking. How about only ten years and I'll give you back the other ten?"
So God agreed......
And God agreed.......
The cow said, "That's kind of a tough life you want me to live for sixty years.. How about twenty and I'll give back the other forty?"
And God agreed again......
But the human said, "Only twenty years? Could you possibly give me my twenty, the forty the cow gave back, the ten the monkey gave back, and the ten the dog gave back; that makes eighty, okay?"
"Okay," said God. "You asked for it."
So that is why for our first twenty years, we eat, sleep, play and enjoy ourselves. 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 to you.
