Three churches are situated in a row along water of an enchanted pool. A priest, with some flowers in his basket, swims down to the first church in the row. There he finds the number of flowers that he had in his basket, got doubled by some miracle. So, he offers a certain number of flowers for Jesus sake, and then he swims down to the second church. He finds same miracle there too; so he offers the same number of flowers as he did in the first church, and then he swims down to the third church, same miracle, same offerings, and oops! No flower is left in the basket!
