Seeing little chance of escape, the first frog soon despaired and
stopped jumping. After a short while he sunk to the bottom of the
bucket and drowned.
The second frog also saw no likelihood of success, but he never stopped
trying. Even though each jump seemed to reach the same inadequate
height, he kept on struggling. Eventually, his persistent efforts
churned some milk into butter. From the now hardened surface of the
milk, he managed to leap out of the bucket.
