A priest, a pastor and a rabbi are out fishing on a boat, and the priest says, "I have to go to the bathroom'" He gets out of the boat, walks on water to the shore.
The Pastor says, "Gee, now that you mention it, so do I". He gets out of the boat, walks on water and goes to the shore.
The Rabbi says, "Hey, if they can do it, I can do it!" He gets out of the boat, promptly sinks and drowns.
The Priest turns to the Pastor and says, "Do you think that we should have told him where the rocks were?"
