Here's a hilarious rap video summarizing the competing macroeconomic perspectives of John Maynard Keynes and Friedrich A. Hayek, each pictured above. Note the appearance as bartenders of actors portraying Ben Bernanke and Tim Geitner near the end of the video.
This blogger's favorite line of the video is sung by Hayek, shown at the top of this post holding his Nobel Medal:
"So sorry there buddy if that sounds like invective. Prepare to get schooled in my Austrian perspective."
