On the first day, God created the dog and said: 'sit all day by the door of your house and bark at any one who comes in or walks past. For this i will give you a life span of twenty years.' The dog said: 'that is a long time to barking. How about only ten years and i will give you back the other ten? So God agreed. On the second day, God created the monkey and said: Entertain people, do tricks, and make them laugh. For this i will give you a twenty years life span.' The monkey said: 'Monkey tricks for twenty years? That is a pretty long time to perform. How about i give you back ten like the dog did?' And God agreed. On the third day, God created the cow and said: you must go into the field with the farmer all day long and suffer under the sun, have calves and give milk to support the farmer's family. For this, i will give you a life span of sixty years.' The cow said: 'that is kind of a tough life you want me to live for sixty years. How about twenty nd i will give back the other fourth? And God agreed again. On the fourth day, God created humans and said: Eat, sleep, play, marry and enjoy your life. For this i will give you twenty years. But the human said: 'Only twenty years? Could u possibly give me my twenty, the fourth the cow gave back, the ten the monkey gave back, and the ten the dog gave back; that is makes eighty okay? Okay,said God, 'you ask for it' So that is why for our first twenty years we eat, sleep, play nd enjoy ourselves. For the next fourth 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.
