I picture something chaotic like the Joker's theme in The Dark Knight when I hear a scene like that, but then again my mind instantly went to the scene where The Riddler blew up the Batcave in Batman Forever, so perhaps I'm trying to find something a bit more menacing and, well...less stupid. As to what he would be whistling? Easy. The Ants Go Marching
