A young boy enters a barber shop and the barber 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.
"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.
"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!"
