Able Teacher

When DS was a young chap and was studying in 11th standard there was a Chemistry teacher who found DS totally useless and was obviously extremely vocal of issue.

One day Chemistry teacher asked, DS please tell me answer to following question :

In a village lived a very prudent man and then one day all villagers brought one dead man to him and asked to make that dead man, drink a bowl full of oil.

Question is that how can prudent man make that dead man drink that oil ?

DS, replied in short :

Sir, I'm not that dead yet.

Not liking his answer, Sir asked another question. Okay tell me answer to another one.

He started, When he was in college and next day there was an exam he saw in dream the question paper and sequence of questions. Next day when he went to write the exam the whole sequence was exactly the same as seen in the dream.

So whats the Moral of the story ? .. teacher asked.

DS replied. Sir I think you mean to say that we should stop wasting our time on classes and should begin even day dreaming. Question paper anyway will come in dream ;) ...so why struggle so hard ?

The only sentence after that DS heard in that class was ... Get out !!!
