Before the show goes live, Arthur requests that Murray introduce him as Joker, a reference to Murray's previous mockery. Arthur walks out to applause, but starts telling morbid jokes, confesses to the train murders, rants about how society abandons the downtrodden and mentally ill, and berates Murray for mocking him on the previous segment. When Murray criticizes him and threatens to call the police, Arthur shoots him twice on live TV, killing him; he is arrested for murder as riots break out across Gotham. One of the rioters corners the Wayne family in an alley and murders Thomas and his wife, Martha, sparing Bruce. Rioters in an ambulance crash into the police car carrying Arthur, freeing him; he stands atop the car, dances to the cheers of the crowd, and smears blood on his face in the form of a smile.
