Once three sardars decided to go on a picnic.
When they got there, they realized they had forgotten the soda.
So, the youngest sardar said he would go home and get the soda if the others promised not to eat the sandwiches until he got back.
An hour, a couple of hours, then all day went by.
Both sardars were now very hungry.
Finally one of the sardars said: “Oh, come on, he is not going to be back. Let’s eat the sandwiches.”
Suddenly, the youngest sardar popped up from behind a rock and said “I know that you eat if i go”.
