A couple of my friends forwarded this link to me this morning:
"Fear the Boom and Bust" a Hayek vs. Keynes Rap Anthem
Spearheaded by a former SpikeTV Exec and a George Mason professor, the production value is really really good, and though the delivery of the rap isn't the best, the concise lyrical summary of contemporary economic theory is impressive. This video is extremely smart and worth multiple viewings. It contains a lot of subtle background jokes.
You can view the production team's website (and download the mp3 for free) here.
