Chintu would stammer regularly and so he would keep quiet most of the time. Once while answering his teachers question everyone started laughing on him. Few students were making fun of his stammering, some were bored of the lecture and others didn't want to be left out and effectively everyone was laughing on him. Chintu decided that he will never answer the teachers questions ever again.
Moral of the story: Laughter is the best medicine, only for oneself.
