It is time to lay our nuts aside (Latin, Relinquere nuces). To leave off our follies, to relinquish boyish
pursuits. The allusion is to an old Roman marriage ceremony, in which the bridegroom, as he led his bride
home, scattered nuts to the crowd, as if to symbolise to them that he gave up his boyish sports.
That's nuts to him. A great pleasure, a fine treat. Nuts, among the Romans, made a standing dish at
dessert; they were also common toys for children; hence, to put away childish things is, in Latin, to put
your nuts away.

At present, instead of being laid aside postnuptually, they would be put to work.
