One monk shoulders two buckets of water. Two monks lift one bucket of
water. Three monks have no water! This is a story told generation after
generation, and has much in common with the western saying too many
cooks spoil the broth. When there is one monk in the temple, he fetches
water for himself. When there are two, they share the duty. But as the
third comes, it's hard to divide the responsibilities. Everyone thinks
for himself and nobody fetches water any more. At last, a fire in the
temple teaches them the importance of cooperation. From then on, they
cooperate and have water every day.
