You know her as: Mercedes Benz-loving, self-treating Pawnee parks department worker Donna Meagle
Why we like her: Retta, who's also stand-up comic, doesn't often take center stage on "Parks and Rec," but she plays brilliantly off of pretty much everyone in the cast, often acting a little bit like a Greek chorus commenting on the rest of the action. (She also has one of the best look-at-the-camera faces this side of Jim Halpert.) Donna's live-tweeting of a cheesy horror movie in the "Halloween Surprise" episode this season -- which mirrors Retta's prolific TV tweets -- was a particular standout.
Where else you've seen her: She had a "Comedy Central Presents" showcase several years ago and has made a slew of TV guest appearances, ranging from "Moesha" to "It's Always Sunny in Philadelphia."
