Give me back my daughter!

One day a mum and her eight-year-old daughter were walking along the beach, just at the water's edge, when a huge wave crashed on the beach, sweeping the child out to sea. "Oh God," lamented the mother, looking up at the heavens and shaking her fist. "She was my only child. I can't have more. She was the love and joy of my life and I've cherished every moment she's been with me. Give her back to me and I'll be in church every day. Forever!"
Suddenly an even bigger wave deposited the girl back on the sand. The mother looked up to Heaven and said, "She was wearing a hat!"
