In this episode of "Practical Criticism," Ajay Singh Chaudhary plays the finale of Bertolt Brecht and Kurt Weill's Threepenny Opera for Rebecca Ariel Porte, who, as usual, doesn't know what the object of the week will be. They discuss true happy endings and false ones, operetta, satire, Brecht and Weill's avant-garde experiments, and Walter Benjamin's famous declaration that there is no document of civilization that is not also a document of barbarism.    This episode of the Podcast for Social Research was edited by Nechama Winston.
