One sunny day, a priest and a rabbi were walking in a park. They passed a lake and the priest says, "It's nice and sunny, why not go for a swim? We are both men of god, we should not be ashamed of our nudity.

The rabbi agrees, so they strip and dive in. After a while, they decide to get out again, but just as they stroll across the grass the their clothes, a group of children walk pass, including several ones from the priest's and rabbi's congregation.

Quickly, the priest covers his genitals with his hands while the rabbi covers his face.

Out of the corners of his mouth, the priest mumbles, "Why are you covering your face, brother?" The rabbi replies, "Because the children in my community recognize my face, not my penis."
