_______________________________________________________

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 ............

Moral: When you think the other person is dumb, you are making a fool of yourself....
