For geography nerds, it's a valid question: Which country is the squarest in the world? None are perfectly square, as national boundaries are ruled by geographical features like coastlines and rivers, and cultural histories like where people choose to settle and the legacy of invasions.
However, the value in this video goes way beyond the original question. Jay Foreman and Mark Cooper-Jones (previously) start off guessing countries, and gradually slide into a rhythm. Then you suspect that they might be rhyming with each other. Finally it spills into a full-blown comedy song. While there may be no square nations, a lot of them are shaped like animals or something else that you hadn't realized before. They eventually determine which country is the closest of them all to being a square. (via Digg)
