Game Over

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.
