A pastor and two of his deacons are out on the river fishing in their rowboat. Twelve o'clock rolls around, and one of the deacons notices a nice spot on the bank to have lunch. He turns to the others and says, "That looks like a nice spot for lunch. What do you say we have lunch over there?"
The other deacon agrees, and so does the pastor. The deacon stands up in the boat, steps out onto the river and walks over to the bank. The pastor looks on with amazement, and thinks to himself, if his deacon is holy enough to walk on water, surely he can.
The pastor stands up, steps out of the boat, and sinks into the water. The first deacon turns to the second and says, "Think we should have told him where the rocks are?"
