The song is "Gassenhauer" from Carl Orff's "Schulwerk." From Wikipedia: "As with many other pieces from the Schulwerk, it has been used multiple times on television, radio, and in films, including the films Badlands, True Romance, Ratcatcher, Monster, Finding Forrester and, most recently, Michael Moore's Capitalism: A Love Story and The Simpsons 22nd season episode The Scorpion's Tale."
