On tonight's episode of NBC's PARKS & RECREATION entitled "Win, Lose, or Draw", 'The Voice' judge Cee Lo Green guest stars along with "Knocked Up's" Paul Rudd and "Step Brothers's" Kathryn Hahn.

It's election day in Pawnee, and Leslie (Amy Poehler) and Bobby Newport (Paul Rudd) are separated by a razor-thin margin. While everyone waits with Leslie for the race to be called, they ponder their futures, and their new opportunities. Rashida Jones, Nick Offerman, Aziz Ansari, Chris Pratt, Aubrey Plaza, Jim O'Heir and Retta also star. The episode airs tonight, May 10th at 9:30 pm/ET on the NBC network.

Since its premiere in 2009, the critically-acclaimed series has been included on dozens of television critics' Top 10 lists. 2011 was an especially notable year for the show: the series received its first Emmy nomination for Outstanding Comedy Series, was honored by AFI as one of the top 10 Television Programs of the Year, received a Writers Guild Award nomination and was named "TV's Smartest Comedy" in Entertainment Weekly’s 2011 cover story. Additionally accolades include Amy Poehler’s two Emmy nominations for her performance, Television Critics Award nominations for Outstanding Achievement in Comedy, Program of the Year and Individual Achievement in Comedy for Poehler and co-star Nick Offerman.
