One fine afternoon, a very rich man invited Birbal to lunch.........."How did you identify him?" What did Birbal say?One fine afternoon, a very rich man invited Birbal to lunch at his house. Birbal, never wanting to disappoint anyone, went to that man's house and he was greeted warmly in a hall filled with people. "I had no idea that there will be so many other guest present here." commented Birbal since he hated large gatherings. "Dear Birbal, they are not guests. All, except one of them are work here for me." told the wealthy man with a cunning look. The rich man then asked, "Can you tell which of them the guest is?" "Perhaps I could," responded Birbal. "Go on...talk to them and I would observe them as you talk, maybe tell them a joke." added Birbal. The rich man recited a joke that was the worst that Birbal had ever heard. As he finished, everyone in the hall laughed hilariously. "Now tell me which of them my other invitee is?" said the rich man as he finished telling his bad joke. And Birbal pointed his finger at a man. The stunned man asked, "How did you identify him?" What did Birbal say?
