* "Kirk" is the Scottish word for church. (Scotty might know this) So we have a church and two chapels (Christine and the wedding ceremony room from "Balance of Terror") on the Enterprise.
* There are at least two Leonards (Nimoy and McCoy, and sometimes Mark Lenard) and two Jameses (Doohan and Kirk) on set, yet neither real actor portrays the character with their first name. So I imagine a moment where someone yells "Leonard!" and both Kelley and Nimoy's heads pop up, and the guy goes, "I mean Real Leonard, not Fake Leonard."
