The father of a 5-year-old boy came home from work, fell into his TV 
recliner, and clicked on the remote. His son came up to him and 
asked, "Daddy, how much do you make per hour at work?" 

The father, slightly annoyed by the interruption, answered, "I make 
about twenty dollars an hour." 

With that, the 5-year-old asked, "Daddy, can I borrow ten dollars from 
you?" 

The father was annoyed, and sent his son to his room. After thinking 
about it for a while, the father changed his mind. 

He went to his son's room and said, "Son, here is the ten dollars you 
asked for." 

The little boy was very happy and pulled out another ten dollar bill 
he had hid in his pillow. He showed the $20 to his dad and asked, 
"Dad, can I pay you this twenty dollars to spend an hour with me?"
