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.
On the second day, God created the monkey and said: "Entertain people,
do tricks, and make them laugh. For this, I'll give you a twenty-year
life span."
The monkey said: "Monkey tricks for twenty years? That's 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'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.
On the fourth day, God created man and said: "Eat, sleep, play,
marry, and enjoy your life For this, I'll give you twenty years."
But man 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 the 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 grand-children. And for the last ten years, we sit on the front
porch and bark at everyone.
