U.S. first lady Michelle Obama will make a cameo on the Season 6 finale of "Parks and Recreation," NBC said Thursday. Obama's appearance in the hourlong episode, titled "Moving Up," will air April 24, the network said. The first lady's part was filmed this month while she was in Miami promoting healthier out-of-school programs as part of her "Let's Move" initiative. "Parks and Recreation" star Amy Poehler appeared with Obama at that event. Vice President Joe Biden appeared on the situation comedy show in 2012, as have Sen. John McCain, R-Ariz., Sen. Barbara Boxer, D-Calif., and former Sen. Olympia Snowe, R-Maine.
