A priest , a monk and a rabbi were out for a day of fishing. After getting into the boat they had just pulled away from the dock when the rabbi said "stop the boat I forgot the coffee". The priest who was driving the boat said "I will turn around and take you back to the dock" and the rabbi said "oh no need I will be right back".The rabbi quickly jumped out of the boat and ran across the water to shore and then to his car to fetch the coffee and then ran back across the water and got back in the boat.
Well the priest not wanting to be shown up by the rabbi said "oh my I forgot the sandwiches and quickly jumped out of the boat to attempt running across the water like the rabbi but instead sank quickly to the bottom of the lake.
With that the monk looked reproachfully at the rabbi and said "you really should have told him where the rocks were".
