Kids these days, with their "emo" and their "MySpace" and their "sexting"! How do you "get down" verbally to show you're "hep"? How about a rap music song!

Actually, while the apparent vogue of rap-based explainers is a little weird, we can't complain too much about this one, since it brought us the line "oil's fungible, fool!" It brings up and dispenses with a lot of the main fallacies about oil prices, with only a little bit of oversimplification and a solid helping of hideously tortured cadence. If you have a friend who likes to wave around Atlas Shrugged while dressing like Super Mario, and you want to set him or her straight on oil prices, this might be the video for you.
