An old Toad once informed all his neighbors that he was a learned
doctor. In fact he could cure anything. The Fox heard the news
and hurried to see the Toad. He looked the Toad over very
carefully.
"Mr. Toad," he said, "I've been told that you cure anything! But
just take a look at yourself, and then try some of your own
medicine. If you can cure yourself of that blotchy skin and that
rheumatic gait, someone might believe you. Otherwise, I should
advise you to try some other profession."
