Two beggars are sitting side by side on a street in Mexico City. One has a cross in front of him, the other one the Star of David.
Many people go by and look at both beggars, but only put money into the hat of the beggar sitting behind the cross.
A priest comes by, stops and watches throngs of people giving money to the beggar behind the cross, but none to the beggar behind the Star of David.
Finally the priest goes over to the beggar behind the Star of David and says: "My poor fellow, 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 behind the Star of David turns to the beggar with the cross and says, "Moishe, look who's here to teach the Levine Brothers about marketing!"
