And there was the indigent cobbler who had a bad cold. He went to the Doctor to ask for some relief, so that he could continue to work, but admitted that he had no money to pay for the treatment at the moment. The doctor told him that, without money, he would not provide medicine and to go away, that the cold would soon clear up.

Some months later, the Doctor's shoe lost its heel leather as he was on his way to an important dinner. He was not carrying his wallet, but he went into the shoe shop and asked if he could have an emergency repair, but that he was unable to pay spot cash.

The cobbler, of course, said, "Physician, heel thyself."
