Parks and Recreation, NBC's faux political comedy set in small-town America, will air a special Beltway episode next week, featuring three notable U.S. senators: John McCain, Olympia Snowe, and Barbara Boxer. The trio will appear in a cocktail party scene with Amy Poehler and Adam Scott. The former Republican presidential nominee is no stranger to the entertainment world: he famously appeared on Saturday Night Live in the midst of his ailing presidential bid.
