A Lutheran pastor, a Catholic priest, and a professional poker player were fishing from a boat not far the shore of a lake. The pastor needed to go to the bathroom so he got out of the boat, walked across the water, disappeared into the woods by the shore. He then walked back across the water to the boat and climbed back in. The priest was the next to make the trip, getting out of the boat, walking across the water, disappearing into the trees, and then walking back across the water and returning to the boat. The professional poker player was the last to go. He stepped out of the boat and immediately sank. . . . . . . . . . . . . . The pastor looked at the priest and said, "We really should have told him where the rocks are."
