An entrepreneur comes at a barber to cut his hair.

After he finished negotiating with the barber, the barber's activities begin. The barber told me many things while working so that customers feel comfortable.
Until the barber told me that near the house there is a kid who thinks the world's most stupid.
The businessman was surprised and asked: "What you say is why he is the world's stupidest kid?"
"If you do not believe, I shall call and show that he is very stupid"
Shortly thereafter, the boy in question melintaslah the barber. Then summoned the boy to come closer.
Soon the barber offers two sheets of paper currency to the child, 1 sheet 1 sheet 2 thousands and 10 thousands. "Please you choose between 2 sheets of paper money, what you choose you should have" said the barber.
Stupid kid immediately he took the money 2 thousands and leave immediately. With a triumphant smile barber said to its customers, "do not you think I said, he is a child of the stupidest in the world, has repeatedly I tried and I always succeed, he always took the money that the smaller the value, if he's smart he should choose the greater one".
The businessman had just quietly listened barber. In his heart he wondered why the child was always taking money less when given a choice by the barber.
Once completed barbershop, the businessman looking foolish child to ask the reason of his choice who is not right for him.
He met with the child stupid and asked: "Son, what caused you always choose a currency whose value is smaller when given a choice by the barber".
Then the entrepreneur alarmed when he found the answer to the child.
"I deliberately chose the smaller sum that I was considered stupid by a barber, he was always curious and always wanted to try, so he always tell people that he was able to joke, and I also gained did not matter because I can always money thereof. If I choose a larger money then he was no longer curious, then permaiananpun ended and I became no longer receive extra pocket money. "

So the businessman thought he asked "if you have this, then who exactly is more stupid? and who is smarter? "
