Two beggars are sitting on a street close to the vatican, each holding out their begging bowls one evening, one is wearing a bracelet with a large, carved wooden crucifix around his wrist, and his bowl is brimming to the hilt with coins, even a fair few bank-notes, the beggar sitting beside him has a completely bare, empty bowl, and around his wrist, is a golden star of david.
On his way back from St.Peter's, after giving a speech, the pope walks by, and feels rather sorry for the beggar wearing the star of david.
So, he stops to talk to the beggar, and out of charity, gives him a generous donation in alms, seeing that he has nothing, and not wanting him to go hungry. The pope then says to the beggar waving the star of david 'Sir, this is a catholic country, your star of david is not going to encourage our devout catholic population to give you any money, in fact, they are likely to give more to the beggar-man here at your side just to spite you'.
The beggar with the gold star of david dangling from his wrist prominently says to his fellow beggar 'oi vey Moshe! look who's lecturing the fucking Goldstein brothers about marketing techniques', as the other beggar chucks away the crucifix down the nearest drain, dons a yarmulke, they both shuck off their dirty ragged clothing to reveal smart pinstripe suits, hand the half bottle of cheap whiskey in a paper bag to the pope, whilst they pull out a corkscrew, open up a bottle of vintage champagne and walk away laughing their arses off.
