Next time you're bored on the couch and trying to decide what to watch, check out the "Mind Over Money"
episode of NOVA. It's a pretty good overview of the different perspectives that traditional and behavioral economists have on financial markets, and it illustrates a number of experiments about the creation of bubbles and such. Perfect for some nerdy date-night viewing.
When you're done with that, you could also put on the Freakonomics documentary.
