Answer: The grandmother takes her grandson to the beach and falls asleep, while she is sleeping a huge wave comes in and sweeps the boy out to sea. Grandma wakes up to find the boy gone and begins to pray "Lord, if you bring him back, I will do anything you want." Another huge wave comes in and deposits the boy safe and sound in front of the grandmother and she looks to heaven and says "he had a hat on, you know!"
