Test conducted, next day…

Tom – Pay attention! Not a single student got good marks, Bob what happen, why you are not studying.

Bob – Sorry sir, our honorable Prime Minister Narendra Modi has changed the currency that is why I am not studying.

Tom – Modi has changed the currency, but how it affected your studies.

Bob – Sir, I am scared that PM Modi always keeps on changing something and the other. If I had learned my syllabus, who knows what comes in his mind the next day he may change the syllabus also.

Tom –you fool! Next week your exam will start, prepare nicely for it.
