The Grand Duke Revival

Ludwig (an actor) replaces the company manager, Ernest, and then he replaces the miserly Grand Duke Rudolph of Pfennig Halbfennig, after "killing" each of them by drawing the ace from a deck of cards in two "statutory" duels. By winning the statutory duels, Ludwig assumes all of Ernest's and Rudolph's rights and obligations. Soon he finds himself with far more wives, and prospective wives, than he knows what to do with. In the end, a lawyer solves the problem.
