A young boy enters a barbershop

A young boy enters a barbershop 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 coins?”

The boy  his cone and replied,

“BECAUSE THE DAY I TAKE THE FIVE RUPEE COIN, THE GAME IS OVER”
