A day before his 15th birthday, the son of a wealthy family was asked by his father, `Well my son, what would you like for your birthday?'
The son hesitated a moment and his father's thoughts leapt ahead to a new computer and similar things. However, his son had had a new computer only recently and could have a new one any time he wished.
Finally, the son said, `Father, I have everything a boy could wish for, but there is one thing I would really like. I would love to have a pink ping pong ball.'
The father was rather astonished at this wish, but said, `If it is a pink ping pong ball that you want, a pink ping pong ball you shall have.'
And so, the next day, the son was given as his bithday present a pink ping pong ball.
The boy took the ball to his room and the next morning the pink ping pong ball was gone. The father was mildly surprised but decided not to say anything. The pink ping pong ball, however, was never seen again.
The next year, a day before his 16th birthday, the father asked his son what he would like for his birthday.
`Father,' replied the son, `I have everything a boy could possibly wish for, but there is one thing I would really, really like. I would love to have a tenpack of pink ping pong balls.'
The father was more surprised than the year before, but kept his curiosity at bay, for he knew that his son had a right for privacy. he said therefore, `If it is a tenpack of pink ping pong balls that you want, a tenpack of pink ping pong balls you shall have.'
And so, the next day, the son was given as his birthday present a tenpack of pink ping pong balls.
The boy took the tenpack of balls to his room and the next morning, not a single ball remained, merely the empty husk of the tenpack. The father wondered where ten pink ping pong balls might disappear to, but decided not to say anything. The pink ping pong balls, however, were never seen again.
The next year, a day before his 17th birthday, the son was asked by his father what he would like for his birthday.
`Father,' said the son to this, `I have everything a boy could wish for, but one thing would make my happiness complete. I would dearly want a carton of pink ping pong balls.'
The father was beyond surprise, but decided to make sure he had not misheard. `A carton of pink ping pong balls?'
`A carton of pink ping pong balls,' the boy confirmed.
`I can't understand your fascination with pink ping pong balls,' said the father, `but if it is a carton of pink ping pong balls that you want, it is a carton of pink ping pong balls that you shall have.'
And so, the next day, the boy was given as his birthday present a carton of pink ping pong balls.
The boy was delighted and took the carton to his room. The next day, miraculously (as if by magic, even) the pink ping pong balls had all disappeared.
`Dear son,' said the father, `I must ask now, what do you do with all those pink ping pong balls?'
The son, however, was reluctant to tell him. `Please humour me, dear father.'
The carton of pink ping pong balls, however, was never seen again.
The next year, it was clear that the son would get a car, but the father felt that, perhaps, his son also had some other wish apart from the obvious. So, one day before the son's 18th birthday, the father asked him whether he had a special wish for his birthday.
`Dearest father,' the son started, `I have everything a young man could possibly want, but there is one craving in me. I would, more than anything, want a warehouse full of pink ping pong balls.'
One of these years, his father thought, I should get to the bottom of this. However, he decided to humour his son's wish. At least he had been wise enough to buy shares in a pink ping pong ball factory.
The next day, the son was given the address of a warehouse where all his new pink ping pong balls were stored. The son was delighted and decided to spend the next night in the warehouse rather than at home.
The following morning, the son stepped out of the warehouse, but it seemed to be empty otherwise. The father had a closer look and indeed, apart from empty cardboard boxes, nothing was left inside the warehouse. No pink ping pong balls were left.
The following year, one day before the son's 19th birthday, the father braced himself for another warehouse of pink ping pong balls. He asked his son what his deepest desire was and he had not been entirely wrong.
`Father, you have made me very happy these last years and this year I ask of you a shipload of pink ping pong balls if at all possible.'
It was possible, if only because the father had by now bought each and every factory of pink ping pong balls in the country.
The next day, the father took his son to the harbour and showed him a huge tanker and told his son that there were millions, billions, trillions of pink ping pong balls in there.
`Father,' the son said, `You've made me very happy yet again.'
That night, the son spent on board
