Kevin and Dan talk about one of the seminal episodes of all of Star Trek--Errand of Mercy, which introduced one of the best sci-fi protagonists of all time--the Klingons. They also talk about the Cold War influenced story line and why guest star John Colicos became a legend in two different classic sci-fi franchises--Star Trek and Battlestar Galactica. And why maybe Kirk and Spock need to better pay attention to some of the small details.
