The rabbi of a very poor temple was trying to figure out why his congrigation was so poor and the Roman Catholic church down the block was so well off.  Then, in comes his son.

The rabbi decides to send his son to the RC church on Sunday on the chance that he could get some idea how they collected so much money.

The son comes back and says "It's easy pop!  There is a guy in special robes on the stage in the front of the church, and he turns to the audience and hollers 'I bet I can beat you in a game of dominos.' Then a guy in the balcony answers 'I bet you I can beat YOU in a game of dominos.'"

The rabbi asks "so, what do they do then?"

The boy says "then a bunch of fellows go up and down the aisles collecting the bets in baskets!"
