I doubt there are many Country Life readers out there who aren't already familiar with the show, either from watching it or from having friends refer to taglines in conversation — "Put a bird on it!" — or post clips to their Facebook walls — "Is it local?"
Or perhaps you caught Brownstein and Armisen's interview with Terri Gross on Fresh Air last week, in which they talk about the various ways the fussy, self-serious, propriety-vigilant characters they play on the show are more or less themselves. Brownstein, for her part, manages to call attention to all the local actors they use on the show, right before Gross plays the "Is it local?" clip, which is basically a send-up of fanatical locavore-ism. (Also, the transcript of the interview contains a funny typo: "Oy! Not soy!" Since the allergy sufferers quoted are punks, not Jews, that should be "Oi!" not "Oy!" Anyway. I suppose pointing that out sort of makes me a Portlandia type, doesn't it?)
