Said when golden coaches return to their inherent pumpkinness.
BTW in the movie "Patton" the general explains that when a legion returned to Rome in triumph, the general of the legion would lead a parade past the emporer. Riding in the chariot next to the general was a slave who held a golden wreath over the general's head. The wreath signified his triumphs. At the same time the slave whispered in the general's ear, "Sic transit gloria mundi".
My particular favorite was Caesar's oft used phrase in his Gallc Commentaries, "Quae cum ita sunt".
