The Monkey and the Dolphin
A group of sailors set sail on a long voyage. They brought along a monkey to keep them company. After several weeks at sea, there was a terrible storm. The choppy waves tossed around the small ship, and both the sailors and the monkey were thrown into the sea.
A dolphin saw the monkey in the water and rescued him. The dolphin swam to a nearby island, carrying the monkey on her back. When they arrived at the island, the dolphin asked, "Have you been here before?"
The monkey said, "Yes, I have. Actually, I am the king of this island." Of course, that was not true. In fact, no one lived on the island at all.
The dolphin replied, "Good. Then you no longer need me." And she swam off, leaving the monkey stuck on the island.
