“"Nasruddin, four years ago you were here, and I asked that time also what is your age, and you told me forty years. Now this is absolutely inconsistent – how can you still be forty?" Nasruddin said, "I am a man of consistency. Once forty, I remain forty always. When I have answered once, I have answered forever! You cannot lead me astray. I am forty, and whenever you ask you will get the same answer."”
