a father came home and his little boy was waiting by the door. he tugged on his dad's coat and asked 'dad, how much do you earn an hour?' a little annoyed, the father replied '100$ an hour. why?' the little boy said, 'please may i have 50$?' angrily, the father shook his head and walked away, wondering why a little boy would need so much money. that night he felt bad and went and saw his son. he pulled out a 50 and handed it to the boy. the little boy rummaged under his pillow and pulled out five crumpled 10$ bills. he handed it over to his dad and said 'can i have an hour of your time?'
