She stopped by Jimmy Kimmel Live to discuss the cast's political reunion last October, which had the Internet abuzz demanding a grander get-together. "It was all top secret, we were wearing hats and sunglasses," she said. "And we got there and we just started humping each other."

Of course some of the original show's best moments came from their guest stars, whom Mullally said were always great to work with--even if Madonna didn't know her real name and Cher was lifted by a crane on and off the set before anyone could make small talk with her. Watch, below.
