A mother was watching her four year-old son playing outside in a small plastic pool half-filled with water. He was happily walking back and forth across the pool, making big splashes.

Suddenly, the little boy stopped, stepped out of the pool, and began to scoop water out of the pool with a pail.

"Why are you pouring the water out, dear?" asked the mother.

"Because my teacher said Jesus walked on water, and this water doesn't work," he replied.
