Once upon a time, Erich Segal wrote a book called Love Story, which brought him much success and no little fame. This was his first Fairy Tale.
Once upon a time, a young and innocent hero set forth on a quest. It lead him to the lair of a wicked villian, the sort of man from whom you wouldn't buy a used car. And yet, our hero did buy a used car and lived happily ever after. Which is why this is a fairy tale.
