Little John 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 little John over and asks 'Which do you want, son?'

Little John 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, John! May I ask you a question... why did you take the quarters instead of the dollar bill?'

Little John licked his cone and replied 'Because the day I take the dollar, the game's over!'
