Doctor Foster went to Gloucester, In a shower of rain; He stepped in a puddle, Right up to his middle, And never went there again. (Nursery Rhyme, c.1844)
Suppose a man was walking down a street one day in torrential rain. The road has become like a river. As he crosses the road, the ground opens up beneath him; a sink hole had developed under the swollen waters. Plunging down through the water to chest height he lands on a craggy, uneven surface. His leg is broken in several places.
