There were three preachers: a Catholic, a Baptist, and a rabbi. They are all fishing out in the lake when all of a sudden the Baptist has to go to the bathroom. So he gets up and walks across the water, does his business, and comes back. Then all of a sudden the rabbi has to go, so he gets up and walks across the water, does his business, and comes back.
Then the Catholic has to go, but when he gets out he falls into the water, so he swims back, gets back into the boat, looks up, and says, ''God, let me walk across the water.'' Then he tries again and falls into the water, so he swims back, tries again and he falls again.
The Baptist leans over to the rabbi and says, ''Do you think we should tell him where the stepping stones are?''
