dumbest kid in town

A young boy enters a barber shop and the barber whispers to his customer 'This is the dumbest kid in town.... 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 ream 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!'
