During an appearance last week at the NBC Experience Store, Parks and Recreation's Nick Offerman, the man behind the legendary Ron Swanson, took some time out from signing autographs to comment on the various Parks & Rec merchandise for sale in the store. Now that we have the beginnings of a cookbook and a Pyramid of Greatness, it's only fair that we get some fashion tips from the man, too. He cracks wise about the Harvest Festival, Duke Silver, MouseRat, essentially becoming the best pitchman for NBC products imaginable.
