That kid never learns

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 is over!”
