Dan and Kevin list the many reasons why this episode is a notorious dud from the first season, including Kirk becoming the dumb captain, Lazarus' beard that keeps changing shape, and why if you're not feeling well, maybe just stay the hell away from the edge of cliffs. And how this is connected to Drew Barrymore.

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.

Kevin and Dan talk about one of the best episodes of the Original Series, why neither one of us would stick around if a monster was burning people to death, and Kevin takes the quiz from Dan as to how many of the original 12 star ships Kevin can name in 60 seconds. Which begs the question--how many of them can you name? And, Dan sends some cool Trek merch Kevin's way.

Dan and Kevin also mention why this episode is William Shatner's favorite, and why Nimoy stopped talking to Shatner for a while after filming this, which may have laid the seeds for their estrangement at the end of Nimoy's life.
