"For example, throughout the long contest, extending over several decades, on the free [silver] coinage question, the existence of this motto on the coins was a constant source of jest and ridicule; and this was unavoidable. Everyone must remember the innumerable cartoons and articles based on phrases like 'In God we trust for the other eight cents'; 'In God we trust for the short weight'; 'In god we trust for the thirty-seven cents we do not pay'; and so forth and so forth. Surely I am well within bounds when I say that a use of the phrase which invites constant levity of this type is most undesirable."
