Improv group Upright Citizens Brigade performs their famous "Asssscat" show live, with original members Amy Poehler, Ian Roberts, Matt Besser and Matt Walsh. Based on one-word suggestions from the audience, the troupe -- with assistance from comics Andrew Daly, Sean Conroy, Chad Carter and Horatio Sanz ("Saturday Night Live") -- creates unrehearsed, on-the-spot hilarity that's as smart as it is funny.
