A priest, preacher, and a rabbi...

A priest, preacher, and a rabbi decided one day to go on a fishing trip early in the morning. So the three of them went to a nearby lake and cast out a small row boat in the middle of the lake. Now it was getting to be around midday, and the sun was beating down on the three men. The priest suddenly stood up and exclaimed "My, it is becoming a very hot day and we forgot to pack some drinks. I am going to go the store and get some soda for myself." So the priest jumped off the boat, walked on the water to the shore, went to the store and bought a soda. He then came back to the boat the same way and once again started to fish. The preacher after some time told the other two that he was feeling thirsty as well and will be going to the store. So the preacher stood up, jumped off the boat, walked on the water to the shore, went to the store and bought some water. Like the priest, he came back to the boat and began to fish. The rabbi saw what the other two did and sat there in disbelief. He couldn't believe that they both were able to walk on water. So he said to them, "Hmph it is so easy to walk on water anyone can do it. I am also going to go to the store to get something to drink." So the rabbi jumped out of the boat and then began to flail around in the water. The priest and the preacher looked at each other. The priest then asked the preacher, "Should we have told him about the stepping stones?"
