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 2 pound coin in one hand and two 50ps in the other, then calls the boy over and asks,
“Which do you want, son?”
The boy takes the two 50ps 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 next to an ice cream van.
“Hey, son! May I ask you a question? Why did you take two 50ps instead of the 2 pound coin?”
The boy licked his ice cream cone and replied,
“Because, the day I take the 2 pound coin, the game is over.”
