The Game is 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 rupeecoins(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 ofthe 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..
