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.
