There are more churches in Las Vegas than Casinos. During Sunday services at the Offertory, some worshipers contribute Casino Chips as opposed to cash.
Some are sharing their winnings - some are hoping to win. Since there are so many Casinos, the Catholic churches send all the chips into the diocese for sorting.
Once sorted for the respective casino the chips belong to, one junior priest takes the chips and makes the rounds to the casinos turning chips into cash.
And he is known as the chipmonk.
