When fans think of Klingon episodes on TOS, they think of “Errand of Mercy,” “Day of the Dove,” and “The Trouble with Tribbles.” The second appearance of the classic villains was made in what is really a Bones story—they just happen to be there. “Friday's Child” gets overlooked by fans, yet it builds upon the Organian Peace Treaty and allows Dr. McCoy to step into the spotlight all at the same time. In this episode of The Ready Room, we’re joined by Larry Nemecek, Charlynn Schmiedt, and Zachary Fruhling to discuss the other Vasquez Rocks show, those dastardly Klingons, wearing carpet in the desert, how Dorothy Fontana handles the symmetry between Kirk, Spock, and McCoy, and whether or not “Friday’s Child” is the most undervalued TOS episode. In our news segment, we discuss the recent Beverly Crusher Day and upcoming Deanna Troi Day, more from the Star Trek Beyond Dubai set and its alien faces, and we discuss the StarTrek.com poll that asked which series has the saddest episodes.
