"Mind your own business, Spock. I'm sick and tired of your half-breed
interference."
-- Kirk
PLOT
Nurse Chapel's long-lost fiance, Roger Corby, turns up in control of a
mechanism capable of producing android replicas of live beings. Kirk is
copied on a horizontal wheel, and Dr. Corby wants to place his android
Kirk in control of the Enterprise. Kirk puts all his thoughts into Vulcan
bigotry as he is being copied, in hopes that the copy will think insulting
Spock is a commonplace occurrence.
Rock is a smarter android left behind by "the others", but doesn't know how
long he's been around. Mention is made of Kirk's brother George Samuel
Kirk ("Only YOU call him Sam").
FACTS
Rock is played by the actor who portrayed Lurch on "The Addams Family"
television show, not to be confused with Lwaxana Troi's servant in "Star
Trek: The Next Generation", who played Lurch in the "Addams Family"
movie.
