A child entered the barber shop, the barber man said in his client's ear:
This is the stupidest child in the world
I will prove it to you now
The beautician then placed a $ 1 bill in one hand and a 25-cent coin in the other, and told the child which one he wanted.

The child picked up the 25-cent coin and went out. The customer saw the boy after leaving the barber shop and asked him:
Why do you pick up a 25 cent coin every time ?!

The boy replied: Because if I take a dollar, the game is over
