From cheleshere on Experience Project:
Two beggars were sitting side by side on a street in Rome. One held a Cross in front of him; the other one was holding the Star of David. Many people passed by, looked at both beggars, but only put money into the hat of the beggar holding the Cross.
The Pope came by and stopped to watch the number of people giving money to the beggar who held the Cross, while none gave to the beggar holding the Star of David. The Pope approached the beggar with the Star of David and said, “My poor fellow, don’t you understand? This is a Catholic country; this city is the seat of Catholicism. People aren’t going to give you money if you sit here with a Star of David in front of you, especially when you’re sitting beside a beggar who is holding a Cross. In fact, they would probably give more money to him just to prove a point.”
The beggar with the Star of David listened to the Pope, smiled, and turning to the beggar with the Cross, said, “Moshe, look who’s trying to teach the Goldstein brothers about marketing!”
