Just before a boy enters the barbershop, the barber tells his customer, "This is the dumbest kid in the world. Watch." The Barber puts a dollar in one open palm and two quarters in the other and asks the kid, " Which do you want?" The boy takes the quarters and leaves.
"See?" says the barber, laughing.
Later, the customer passes the boy, who is standing outside a candy store. "Why'd you take the quarters and not the dollar?" he asks.
"Because," says the boy, "the day I take the dollar, the game's over."
