The Joker's infamous song from Batman: Arkham Origins. This scene is included as one of the death scenes that happens during the game when you die. The song is a parody of "Ding Dong! The witch is dead." from The Wizard of Oz. I'm not sure if you can get it at any point or if it's just during a mission to do with Joker that you get this game over. You see, Arkham Origins is the only game in the Batman: Arkham series I haven't played yet.
