Once Tenali was invited to dinner by a rich man. When Tenali reached there, he found himself in a large crowd. The host greeted him warmly and took him inside. Tenali said, “I did not know that there would be so many guests in this gathering.” The host replied politely, “They are not guests, Sir. They are my employees except one who is the only other guest here besides you. Could you tell who that another guest here is?” “Maybe, I could.”
“Tell me who the other guest here is.” Tenali pointed out towards a man and said, “He is that other guest.” The rich man was very surprised. He was puzzled as to how he could recognize the other guest. He said to him, “You are right, Tenali; but how did you recognize him?” Tenali said, “Because only employees can laugh on such a joke as cracked by you. He was the only person who did not even smile on your joke, so I immediately recognized him as the other guest.”
