I was listening to The Traffic Song and it made me think of this story. :P I'd assign it as the theme song but maybe Iron Lion Zion should be the theme song due to Larry's choice. I don't know because I don't think I've ever heard it, so I say it should be The Traffic Song. :P
Also, in the first chapter we find that Harold has been infiltrating the KotOS series for far longer than we thought! :P
