Everyone's favorite mustached government employee Ron Swanswon (Nick Offerman) on Parks and Recreation has already deal with plenty of grief from his wife Tammy (Megan Mullally), but that's not the only Tammy that Mr. Swanson found himself married to in the past. As a matter of fact, Swanson's first ex-wife is also named Tammy and apparently she's an even bigger bitch than the second. The character was obscured but revealed at the end of the second season finale a couple months back, but now we know who will finally be terrorizing Swanson come the third season premiere this fall. Patricia Clarkson (Easy A, Whatever Works) will play Tammy 1 in two episodes of the comedy's third season. More details after the jump.

As for what to expect from Tammy 1 and just how she'll mess with Ron Swanson on the series, executive producer Michael Schur tells TV Line, “We talked about pretty much every possible iteration of who she is and what her backstory is and all we knew is that we didn’t want to do the same thing we did with Tammy 2. Tammy 1 is her own specific brand of demon. I think we came up with backstory for her that’s both funny and illuminating and also answers all of the questions that you would have when seeing people’s reactions to her presence in the finale. I've loved Clarkson's recent comedic work in films like Easy A and Friends with Benefits, so I can't wait to see what she brings to Parks and Recreation when the new season premieres on September 22nd.
