A Jewish grandmother is babysitting her grandson at the beach. He has his pail and shovel and is digging in the sand on the ocean's edge like any child would. All of a sudden a gigantic wave barrels in from the ocean, scoops up the child, his pail and shovel and sweeps them out to sea. The horrified grandmother shrieks in horror and starts pleading with God: "Please, please my grandson, save him! You're a merciful God, and he is only a child." Finally a gigantic wave comes in from the ocean and deposits the little boy with his pail and shovel exactly where he was before.
The grandmother looks him over with great relief and then she yells at God: "Where is his hat? He was wearing a hat!!"
