Everyone’s favorite Pawnee sleazebag Jean-Ralphio apparently has a twin sister, and she’ll be appearing in a future episode of Parks and Recreation, Entertainment Weekly reports. Jean-Ralphio’s twin, Mona Lisa, will be played by none other than Jenny Slate, a wildly-funny stand-up who you may recognize from Saturday Night Live, Bored to Death, and her Marcel the Shell with Shoes On short films and books. In an episode set to air later this season, Mona Lisa will get a job as a saleslady at Tom Haverford’s Rent-A-Swag store. Just when you thought this show couldn’t top having Joe Biden as a guest star, they go and hire Jenny Slate to play Jean-Ralphio’s sister.
