the tortoise and the hare
The Tortoise and the Hare (also known as The Hare and the Tortoise) is one of the most famous of Aesop's Fables.
The story concerns a hare who ridicules a slow-moving tortoise and is challenged by him to a race. The hare soon leaves the tortoise behind and, confident of winning, decides to take a nap midway through the course. When he awakes, however, he finds that his competitor, crawling slowly but steadily, has arrived before him.
