It's the first episode of the series and who better to discuss it with the boys than Star Trek author and huge Six Million Dollar Man fan (he still has his copy of The Secret of Bigfoot novelization) Dayton Ward.  In this longer episode, they discuss how "Population: Zero" manages to hit all the marks of an opening episode that establishes the feel of the series.  They also take an in-depth look into the iconic theme music and opening credits.
