"Next, his delight led him gracefully to execute a hop in ballet fashion, so that the wardrobe trembled and a bottle of eau-de-Cologne came crashing to the floor. Yet even this contretemps did not upset him; he merely called the offending bottle a fool, and then debated whom first he should visit in his attractive guise" (Dead Souls by Nikolai Gogol, D. J. Hogarth (trans.), 1842).
