A young boy enters a barber shop and the barber whispers to his customer, “This is the dumbest kid in the town. Watch while I prove it to you.”
The barber puts a five pound note in one hand and two pound coins in the other, then calls the boy over and asks, “Which do you want, son?”
The boy takes the coins 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 shop. “Hey, kid! Can I ask you a question? Why did you take the pound coins instead of the five pound note?”
The boy licked his cone and replied, “Because the day I take the fiver, the game is over!”
