There were two beggars sitting next to each other on the street in Vatican city, one had a large cross around his neck, the other had the star of David.
It was a sunny day, there were many people walking past the two beggars. Everyone was giving money to the man with the cross around his neck money, while the man with the star of David got nothing.
One morning a high priest walked by the beggars and said to the beggar with the Star of David,
“My friend, you are in Vatican City and all these people that pass you by will give to the man with the cross, they will never give money to a man with a Star of David, in fact, they will give to the man with the cross just to spite you…”
The beggar with the Star of David turned the beggar with the cross and said,
“Hey, Moshe, this schmuck is trying to teach the Smith brothers about marketing”
