Ping Pong Balls

There once was a boy who was having his birthday. His dad was very wealthy and told his son "you can have anything you want. You name it, you got it" now the son was turning 12 so the father figured it would be a game system and some games but all the son wanted was one pink ping pong ball. The dad followed up on his promise and got the son what he wanted. Next year came 13 and his dad told him the same thing. But this time the son wanted a little more. "Two pink ping pong balls dad" the dad was very confused. He owns one of the biggest businesses in America and can buy anything but his son is so easy to please. He buys the balls but tells his son "I will give these to you but first, can I know what you are doing with them?" The son says "please dad. Can I just have them?" The father hands over the balls. These keeps happening for a few years and before his 16th birthday his dad asks again. This time the answer changes a little bit. "Dad I think I want a garbage truck this year. Full of pink ping pong balls" the father very confused asked" son what would you do with all of those balls?" The son just says "please dad. I just really want them." The dad begins to worry because he is close to having 50 ping pong balls already but they seem to just disappear but he gets his son the truck full and his son is in the truck for a few days and comes back home but all the ping pong balls are gone. On his 17th birthday the dad tells him that he can have anything except pink ping pong balls. "But dad I was kind of hoping you would buy me a ware house full of pink ping pong balls this year." The dad angry at first yells at the son. " I can get you anything but if all you want is stupid ping pong balls then so be it." So the dad buys the warehouse and has it filled with pink ping pong balls. 6 million balls to be exact. He drops his son off because he wants to spend the night there and when the father picks up his son the next morning all the pink ping pong balls are gone. The dad is so furious he just takes the son home and grounds him. 11 months go by and the son is in a horrific traffic accident and is left in critical condition. With 12 hours before he turns 18 the doctor tells his dad "I'm not sure he will make it through the night" the dad starts crying but wants the son to have a good last birthday so he goes in the room and asks his son "what would you like for your birthday this year?" The son says "dad... Can you get me... *cough* one pink ping pong ball?" The dad says yes and goes to the store to buy his son one last gift. As he hands the boy the ball he says "son please tell me what you are doing with all of these balls." His son says "okay. You have been fair my whole life so I owe it to you to tell you. What I have been doing with the pink ping pong balls all these years is.... And he dies.
