A young boy enters a barber shop and the barber, seeing him come in, whispers to his customer; “This is the dumbest kid in the world.   Watch while I prove it to you.”

The barber puts a dollar bill in one hand and two quarters in the other, then calls the boy over and asks; “Which do you want, son?”

The boy takes the quarters and leaves the dollar.

“What did I tell you?” said the barber.  “That kid never learns!”

Later, when the customer leaves, he sees the same young boy coming out of the ice cream store and says; “Hey, son!  May I ask you a question?   Why did you take the quarters instead of the dollar bill?”

The boy licked his cone and replied; “Because the day I take the dollar, the game’s over!”
