The Peacock network’s tie-ins with the Obama administration continue. NBC said today that Michelle Obama will do a cameo on the season finale of Parks And Recreation. Her scene in the episode titled “Moving Up” celebrates healthier out-of-school programs as part of her “Let’s Move” initiative against childhood obesity. The First Lady’s appearance continues a recent trend of NBC team-ups with D.C. heavyweights. She helped goose the ratings for The Tonight Show Starring Jimmy Fallon last week in a sleepover skit with the host and Will Ferrell. And earlier this week Vice President Joe Biden was the second guest on Seth Meyers’ first night hosting Late Night; the Veep followed Parks And Rec star Amy Poehler, whose character famously idolizes Biden. (He also did a cameo on the sitcom that aired shortly after the 2012 elections.) And on February 14, Community star Joel McHale was tapped as host of the White House Correspondents’ Dinner in May. Then there was pre-pinkeye Bob Costas’ pre-Olympics interview with President Obama on February 6. Michelle Obama’s Parks And Rec episode airs April 24.
