Professor Sardar
Sardar Singh was very keen on doing his Ph.D.He was in search of a subject on which no one did any research before! As he was thinking over it, he found a cockroach on the table in from of him. He decided instantly to do a research on the roach. He picked the roach and put it in the centreof the table and said: "Run". The roach ran. He pulled out one leg of the roach, put it again in the centre of the table and said: "Run". The roach ran. He pulled one more leg
of the roach, put it again in the centre of the table and said: "Run". The roach ran. This way the roach tried to run even when it had just one leg. He pulled last leg of the roach, put it again in the centre of the table and said: "Run". The roach could not! Our Professor was satisfied with his studyand started writing his thesis: "When you pull out all the legs of a roach, it cannot hear anymore".
