From Royal Opera House website:
Old, large and lecherous, Sir John Falstaff can’t resist the ladies. But they can resist him, and three of them plot to put an end to his advances once and for all.
After being tossed in a laundry basket and tipped into the Thames, Falstaff is feeling distinctly sorry for himself. But when the plot is revealed, Falstaff accepts the mockery with stoical dignity. After all, as the opera concludes, ‘Tutto nel mondo è burla’ – all the world’s a joke.
