I'm a doctor, not an asteroid belt! :)
My favorite McCoy line is from "This Side of Paradise" where he was under the influence of the spoors:
Sandoval: Well, Doctor, I've been thinking about what sort of work I could assign you to.
McCoy: What do you mean what sort of work? I'm a doctor.
S: Not anymore, of course. We don't need you...not as a doctor.
M: Oh, no? Would you like to see how fast I can put you in a hospital?
S: I am the leader of this colony. I'll assign you whatever work I think suitable.
M: Just a minute. You'd better make me a mechanic. Then I can treat little tin gods like you.
ROFL!
