There is an atheist swimming in the ocean. All of a sudden he sees a shark in the water, so he starts swimming toward his boat. As he looks back he sees the shark turn and head toward him. His boat is a ways off, so he starts swimming like crazy!
He is scared to death, and as he turns to see the jaws of the great white beast open, revealing its teeth in horrific splendor, the atheist screams, "Oh, God! Save me!" In an instant time is frozen. A bright light shines down from above. The man, motionless in the water, hears the voice of God say, "You are an atheist. Why do you call upon me when you do not believe in me?" Aghast with confusion and knowing he can't lie, the man replies, "Well, that's true. I don't believe in you, but how about the shark? Can you make the shark believe in you?"
The Lord replies, "As you wish," and the light is retracted back into the heavens and the man feels the water begin to move again. As the atheist looks back, he can see the jaws of the shark start to close down on him, when suddenly the shark stops and pulls back. Shocked, the man looks at the shark as the huge beast closes its eyes, bows its head and says, "Thank you, Lord, for this food for which I am about to receive." Gulp!
