Spock:
"Pain is a thing of the mind. The mind can be controlled."
McCoy:
"And don't give me any damnable logic about him being the only man
for the job." Kirk: "I don't have to, Bones. We both know he is."
McCoy: "I said, don't tell Spock
I said he was the best first officer in the fleet." Spock: "Why, thank you, doctor." Kirk: "You were so worried about his Vulcan eyes you forgot
about his Vulcan ears."
