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 a kind of a tough
life you want me to live for sixty years.
Let me have twenty years 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 back the other ten." So God agreed (sigh).

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." 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 fourth 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
cows gave back, and the ten the dogs gave back
and the ten monkeys gave back. That makes
eighty, okay?"

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

So that is why for 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 our grandchildren;
and for the last ten years we sit on the porch
and bark at everybody.
