Beside a pond deep in a wooded clearing lived two rabbits who were painters, Paint-by-Day and Paint-by-Night. One drew the reflection of the sky on the water's surface by day, and the other by night. One painted quickly, the other loved to take his time. At dawn and dusk, each would hand his brush to the other, thus bringing on day or night. And so the hours went by. But one day, a big black cloud came to rest over the pond. The rabbits painted its reflection, but to no avail: it wouldn't budge! Time had stopped. Together, the rabbits hopped on their bikes and pedaled backwards to go back and time and fix things.
