Last week’s Sunday Fun introduced Khan Academy. I was browsing through the 3,200 video tutorials available and found some really interesting investing and finance content.

When I saw this, it caught my attention since I have a few friends that think short-selling is the worst thing that ever happened to stocks. When I try to explain, they tune out anything that I say.

This is a really good primer on shorting. I especially like the discussion about cheer-leading.
