A Catholic priest, a Baptist preacher and a rabbi fish in a lake. The preacher has to use the bathroom, so he walks across the water, does his business and walks back. Then the rabbi has to go, so he walks across the water, does his business and walks back.
The Catholic has to go, but when he gets out he falls into the water. He swims back, gets back into the boat, and says, "God, let me walk across the water." He tries again and falls into the water, swims back, tries again and falls again.
The Baptist leans over to the rabbi and asks, "Do you think we should tell him where the stepping stones are?"
