At an interfaith retreat some time ago, the organizers decided to allow
for a free afternoon of just socializing.  A priest, minister, and a
rabbi went fishing together.

After awhile, the priest said, "Brother, Rabbi, would you please both
excuse me, I've got to pee."  He laid down his fishing pole, stepped
over the side of the boat, and *walked across the water to the shore.*
He finished his business, then *walked back across the water* to the
boat.

The minister said, "Father, I didn't want to be the first to have to
go," stood up, stepped over the side of the boat, and walked right on
top of the water to the shore.  He also finished his business, zipped
up, and walked back on the water right back to the boat.

The rabbi was awestruck.  Imagine-WALKING on water!
He thought to himself, "well, if they can do this, so can I!" He excused
himself to the priest and minister, put his pole down, stepped over the
side of the boat . . . and sunk like a rock.

The priest turned to the minister and said, "You think we should have
told him where the rocks were?"
