Once a Sadarji came home with his left forehead bleeding his wife asked him what had happened.

He replied "there was a nail in the window of the bus that pricked me each time the bus jerked", his wife said "then y didn’t u exchanged your seat with some other passengers, that did not know about the nail!

Sadarji replied "How can I exchange my seat when there were no other passengers in the bus other than me".
