Humourist Jokes

A humorist, very confident of his art, claimed that there was no one living who would not laugh at his set of jokes. And if there was a person who did not laugh, he was ready to pay Rs. 1 lakh to such an individual.
Many tried, and went back laughing, but without the prize money. Bhenga Singh went to try his luck. And lo and behold, he did not laugh at all, inspite of the choicest jokes narrated by the humorist. Bhenga Singh got the prize money of Rs. 1 lakh and went home.
After one week, Mrs. Bhenga Singh came back to return the money to the humourist, saying that Bhenga Singh had gone crazy. For the last one week he had been doing nothing but staring at the prize money and laughing.
The humourist was puzzled. He contacted Bhenga Singh to find the reason for his unusual behaviour. "The joke became clear to me only after I reached home," replied Bhenga Singh.
