It was the biggest Parks and Recreation cliffhanger at the end of season three: Who would play Ron Swanson's (Nick Offerman) ex-wife, Tammy 1, a woman so terrifying that Tammy 2 (Megan Mullally) ran for the hills at the sight of her back? Now, it appears we have an answer.

TVLine reports that P&R has cast Patricia Clarkson as Tammy 1 for the new season. You know Clarkson from many film and television appearances, including the "Motherlover" skit from Saturday Night Live and the recent romcom Friends With Benefits.

Happy with this casting? Does Clarkson have enough passive-aggression and plain-old-aggression to make Ron quiver in his boots?
