It's unusual to be involved in something we've podcasted on. We've done a podcast on Muppets, and while both of us know live-hand puppets like Ernie from Sesame Street are operated, neither one of us have ever had our hand in one. We know from our podcast that there are about 120 dead bodies on Mt. Everest, but we've never seen them. We know that Einstein's brain was kept in a jar for decades, the ins and outs of mortgage-backed securities, that the FDA doesn't regulate herbs and that there are some decent theories explaining spontaneous human combustion, but none of these things mean what microlending has to Stuff You Should Know.
