Hey Smarties! We’re taping today’s episode of Make Me Smart live from Seattle. We’ll have the show in your feeds soon. But for now, enjoy a rerun of one of our favorite episodes of the year so far.

Later, we’ll hear from a listener who did the math on the cost-effectiveness of fueling up with diesel vs. gas, and a loyal listener makes us smarter about our own theme music!
