A rabbi and a priest went for a walk in a national park, where they came upon a large lake. Suddenly the rabbi said: "Let's go for a swim. It’s so hot and the water looks really clear and refreshing!"
"But we don't have swimsuits" the priest told him.
"So what?" replied the rabbi, "Let's go into the water as God created us."
The priest thought for a moment and then agreed with him. They took off their clothes, laid them on a piece of grass at the edge of the lake and went in for a dip.
After ten minutes they left the lake and walked back towards the place where they had put the clothes.
Suddenly the two noticed a large boy scout troop resting at the edge of the lake staring at them.
Embarrassed, the priest tried to cover his privates with his hands. He then looked over to his side and noticed that the rabbi was covering his face with his hands.
"What are you doing?!?" hissed the priest, "cover your privates!"
"I don't know how it works in YOUR congregation." Said the Rabbi, "but my people recognize me by my face!"
