A Catholic priest is visiting his rabbi friend, and they go out for a walk. It's a hot summer day, so they decide to swim naked in a river in a secluded spot. But some locals happen to pass by, surprising the two bathers. The embarrassed priest immediately covers his willie with his hands, and the embarrassed rabbi covers his face. When the passers-by have gone, the priest asks the rabbi why he covered his face. "Well," he replied, "around here you get recognized by your face."
