This episode features the scene George Veletsianos tweeted about a while ago. Peter Honig wrote a brilliant meditation on this scene a couple years ago, so there's not much I can add. That enigmatic whistling reminds me of Ennio Morricone and some of his spaghetti western scores. Omar, the whistler, is essentially a cowboy character, although I ddin't actually recognize that until it came up in one of the commentaries. The tune is "The Farmer in the Dell." We know this because he says the closing line, "the cheese stands alone." The line, and the tune, are open to some interpretation. The melody is the same as "A-Hunting We Will Go", which fits Omar's character well. It also fits the futility of the Game on the police end: We'll catch a fox and put him in a box And then we'll let him go This has happened a few times already in the series, and it will again. "A-Hunting We Will Go" comes from The Beggar's Opera, and 18th century drama which, to quote Wikipedia, "satirised politics, poverty and injustice, focusing on the theme of corruption at all levels of society." Another fascinating parallel.
