TOS #16: The Galileo Seven

This is the first episode that is purely a study of Spock's character. After crash landing on a weird planet where this, highly illogical, twelve-foot behemoth terrorizes Spock's science party, Scotty saves the day with a little Twenty-Thousand-Leagues electricity magic.




And the whole bridge crew has a good laugh about Spock's highly logical illogical behavior.
