Amy Poehler started out her career with an improv group called The Upright Citizens Brigade and the group eventually got a gig acting in sketches on Late Night with Conan O’Brien. Poehler wound up playing the recurring character of Andy Richter’s little sister, Stacy, who had serious anger management issues and an obsessive crush on Conan. Her work here made enough of an impression to eventually score her a spot in the cast of Saturday Night Live.
