On
 the first 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 second day God created the monkey. God said,
 "Entertain people, do monkey tricks and make them laugh. I'll give you a
 twenty-year life span." The monkey said, "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.
__________On the third day God created 
the cow. "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 again.__________On the fourth day God created man. God 
said, "Eat, sleep, play, marry and enjoy your life. I'll give you twenty
 years."Man said, "What? Only twenty years? Tell you what, I'll take my 
twenty, and the forty the cow gave back, and the ten the monkey gave 
back, and the ten the dog 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, and enjoy ourselves; 
the next forty years we slave in the sun to support our family; the next
 ten years we do monkey tricks to entertain the grandchildren; and the 
last ten years we sit on the front porch and bark at everyone.
 
 Life has now been explained to you.
