MCCOY: This is professional, Captain. I am preparing a medical log entry on my estimation of the physical and emotional condition of a starship captain. Which requires a witness of command grade.
(McCoy goes to the door and opens it to admit Spock.)
KIRK: Do I take it, Doctor, Commander, that both of you or either of you consider me unfit or incapacitated?
SPOCK: Correctly phrased, Captain. As recommended in the manual. Our reply, also as recommended, is, sir, we have noted in your recent behaviour certain items, which, on the surface, seem unusual. We respectfully ask permission to inquire further
KIRK: Blast it! Forget the manual! Ask your questions.
