Once upon a time, the animals decided they must do something heroic to meet the problems of a "New World," so they organized a school. They adopted an activity curriculum consisting of running, climbing, swimming and flying. To make it easier to administer, all animals took all the subjects.

The duck was excellent in swimming, better in fact than his instructor, and made excellent grades in flying, but he was very poor in running. Since he was low in running he had to stay after school and also drop swimming to practice running. This was kept up until his web feet were badly worn and he was only average in swimming. But average was acceptable in school, so nobody worried about that except the duck.
