The teaser for next week's Parks and Recreation has now hit the internet, and one thing's for certain: next week is going to be epic. Ron's ex-wife Tammy (played by Nick Offerman's real-life wife Megan Mullally) is back. And if you know anything about Parks and Recreation, you know that Tammy is one cold-hearted bitch and her workplace, the library, is the worst possible place on the planet. Oh, and one more thing, apparently Ron Swanson will sport some corn rows. Yup.
