Props to John Gruber for sharing this in his blog:
A grandmother is sitting at the beach, watching her young grandson play in the water. Suddenly, an enormous wave crashes over the boy’s head, and when it recedes, the boy is gone, washed out to sea.
Frantic, the grandmother cries out to God, “Lord, what has my grandson done to deserve this? Please bring him back to me, and I’ll forever be grateful to you!”
Moments later, another enormous wave crashes against the shoreline, returning the boy to the beach, soaked but unharmed. He begins happily digging in the sand, oblivious to what just occurred.
The grandmother looks at the boy, then raises her head to the sky. She shouts, “He had a hat!”
