A father is coming up on his son's 5th birthday. He wants to get him something special but he doesn't know what he wants. He goes up and asks him, "Son, your 5th birthday is coming up and I wanted to get you something special. What ever you want, name it and i'll get it for you." The son thinks for a while and after a couple minutes says "I want 1 blue ping pong ball." The father thought this was odd but he only wanted to make his son happy. He went out and on his son's 5th birthday he gave him the ping pong ball. The son was so excited he screamed with joy, ran up to his room, and the blue ping pong ball was never saw again. The son's 10th birthday was coming up and the father wanted to do something special for him since someone's 10th birthday is a special time in their life, so he wanted to make it extra special for him. The father goes up to him and says "Son I want you to be happy on your birthday so i'll get you anything you want for your birthday." The boy thinks for a few minutes and says "I've decided what I wanted. I want 2 blue ping pong balls." The father still thought it was odd but he just wanted to make his son happy so he got it for him. The son was still as excited as he was on his 5th birthday so he ran up to his room and the blue ping pong balls were never seen again. The son was a bit older now, he was turning 16 next week so the dad wanted to do something special for his birthday, so he asked his son "Anything you want for your birthday you can have, I want this birthday to be special to you." The son thought for a while and after a little bit said "I want 100 blue ping pong balls."
