A story is told of three professional men -- a doctor, an engineer, and a financier--debating which of them belonged to the most honourable and ancient profession.


The doctor said: “Mine is easily the oldest. Don’t you remember that in the beginning Eve was made out of a rib from Adam’s side? Well, there’s a surgical operation for you.”


The engineer said:“Yes, but before that happened, don’t you know the whole world was created out of chaos in six days? Now, there’s an engineering feat for you.”


“Ah! But who created chaos ?” said the financier.
