The king’s son, George II, inherited his father’s tastes [in plus-sized women] as well as his crown. “No woman came amiss to him,” one contemporary snorted, “if she were but very willing and very fat.” His queen, Caroline of Ansbach, shared the second George’s lascivious interests, sometimes even arranging dalliances for him, but always making sure that any mistress she selected was uglier than she. When he was away visiting his Hanoverian homeland, the king always made sure he kept his wife apprised of his sexual exploits. Some of his letters, graphically detailing every conquest, reached thirty pages long! One paramour, Madame von Walmoden, so attracted the king that he determined to bring her back to England with him. “You must love Walmoden, for she loves me,” he excitedly wrote the queen.
The British people had almost as much fun at this king’s expense as they had at his father’s. On one occasion, a beaten-down old horse was turned loose in the streets of London bearing a placard that read: “Let nobody stop me. I am the King’s Hanover equipage going to fetch His Majesty and his whore to England.”
