A dwarf is taken from his homeland and becomes the jester of a king particularly fond of practical jokes. Taking revenge on the king and his cabinet for striking his friend and fellow dwarf Trippetta, he dresses them as orangutans for a masquerade. In front of the king's guests, Hop-Frog murders them all before escaping with Trippetta.
I never knew anyone so keenly alive to a joke as the king was. He seemed to live only for joking. To tell a good story of the joke kind, and to tell it well, was the surest road to his favor. Thus it happened that his seven ministers were all noted for their accomplishments as jokers. They all took after the king, too, in being large, corpulent, oily men, as well as inimitable jokers. Whether people grow fat by joking, or whether there is something in fat itself which predisposes to a joke, I have never been quite able to determine; but certain it is that a lean joker is a rara avis in terris. About the refinements, or, as he called them, the 'ghost' of wit, the king troubled himself very little. He had an especial admiration for breadth in a jest, and would often put up with length, for the sake of it. Over–niceties wearied him. He would have preferred Rabelais' 'Gargantua' to the 'Zadig' of Voltaire: and, upon the whole, practical jokes suited his taste far better than verbal ones. At the date of my narrative, professing jesters had not altogether gone out of fashion at court. Several of the great continental 'powers' still retain their 'fools,' who wore motley, with caps and bells, and who were expected to be always ready with sharp witticisms, at a moment's notice, in consideration of the crumbs that fell from the royal table.
