"Dog's Misery"

Here's one I hadn't heard before:

The Federalists did what they could to stave off defeat. They painted Jefferson as a debauched Francophile; Americans heard that he had fathered mulatto children, prayed to the French goddess of reason, and even experimented on animals at Monticello, or "Dog's Misery," as some called it.
