Here's a couple:
A jewish grandmother and her grandson were taking a walk down the beach. All of a sudden, a large wave comes on shore and sweeps the grandson out to sea. The grandmother immediately drops to her knees and says, "God, why would you do such a horrible thing! My grandson is the most precious thing in the world to me. Please bring him back!" A few moments go by and another wave comes ashore and puts her grandson back on the beach. Elated, the grandmother runs over to her grandson and hugs him tightly. She looks him over, frowns, looks upward and yells, "He had a hat!"
(kinda dumb, but oh well)
