A priest came by, stopped, and watched as many, many people gave money to the beggar with the cross, but none to the beggar with the Star of David. Finally he went over to the beggar with the Star of David and said, "Don't you understand? This is a Catholic country. People aren't going to give you money if you sit there with a Star of David in front of you, especially when you're sitting beside a beggar who has a cross. In fact, they would probably give to him just out of spite."
The beggar with the Star of David listened to the priest and, turning to the beggar with the cross, said, "Moishe...look who's trying to teach us marketing."
