A traveler, fleeing a tiger who was chasing him, ran till he came to the edge of a cliff. There he caught hold of a thick vine and swung himself over the edge. Above him the tiger snarled. Below him, he heard another snarl and behold, there was another tiger, peering up at him. The vine suspended him midway between two tigers. Two mice, a white mouse and a black mouse, began to gnaw at the vine. He could see they were quickly eating it through. Then in front of him on the cliffside he saw a luscious bunch of grapes. Holding onto the vine with one hand, he reached out and picked the grapes with the other.
