My Rabbi just sent out this joke which is pretty clever:
Two beggars are sitting on the pavement in Ireland. One is holding a large Cross and the other a large Star of David. Both are holding hats to collect contributions. As people walk by, they lift their noses at the guy holding the Star of David but drop money in the other guy's hat. Soon one hat is nearly full whilst the other hat is empty.
A priest watches and then approaches the men. He turns to the guy with the Star of David and says, "Don't you realize that this is a Christian country? You'll never get any contributions in this country holding a Star of David."
The guy holding the Star of David then turns to the guy holding the Cross and says, "Hymie, look who's trying to teach us Marketing."
