When viewers and critics first saw the government-hating parks director Ron Swanson on 'Parks and Recreation,' they didn't quite know what to make of him. Is he just a hard-ass? Or was there more to him?

Well, as the show has improved so has viewers' opinion of Ron, played by Nick Offerman. In the first half of 'Parks and Rec's' second season, Swanson has become a favorite of fans and critics; we've seen his love of breakfast food, his ability to build a small harp while drinking, and his secret life as smooth jazz stylist Duke Silver. And the 'stache... oh, the 'stache. It's the best one on primetime since Tom Selleck's.

When I was at the NBC party at the TCAs last month, I spoke to Offerman about how Swanson has developed, having his real-life wife (Megan Mullally) play Swanson's ex, and if we're going to see more of Swanson's jazzy alter ego.

(S01E06) Ah, so that's how they're going to do it. While the pit was still the underlying thrust of the episode, the stories were more about the characters and relationships. And realizing even more what a big dumb sap Mark is. It's really more a testament of Leslie's own insecurities and issues that she's so hung up on him because he is even more lame than Tom. At least Tom is charismatic and charming, in his own creepy way. Mark is just creepy, a lot older than he seems to think and kind of a doofus.
