Sardarji is in Delhi. He is walking on a street which has a Clock
Tower when someone asks him if he wants to buy the clock on the Tower.

Sardarji says "Yes".

"Give me a thousand rupees and I'll go get a ladder."

The man took the thousand and disappeared. Having waited for several
hours the Sardarji figured he was taken for a ride.

On the next day the Sardarji is again walking along the same street
and the same man asks him to buy the clock.

"Give me a thousand rupees and I'll go get a ladder."

The Sardarji gives him the thousand and says "I am not a fool. This
time, you wait and I'll go get a ladder".
