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 five rupee coin in one hand and two one rupee coins (1+1=2) in the other, then calls the boy over and asks, "Which do you want, son?"
The boy takes the two one rupee 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 store.
"Hey, son! May I ask you a question?
Why did you take two one rupee coins instead of five rupee coin?"
The boy licked his cone and replied,
"BECAUSE THE DAY I TAKE THE FIVE RUPEE COIN, THE GAME IS OVER"
