McCoy and Spock in “Unfinished Business”

McCoy

This is the first time in a week I've had time for a drop. Would you care for a drink, Mr. Spock?

Spock

My father's race was spared the dubious benefits of alcohol.

McCoy

Oh. Now I know why they were conquered. What are you worried about? Jim generally knows what he's doing.

Spock

It was illogical for him to bring those players aboard.

McCoy

Illogical? Did you get a look at that Juliet? That's a pretty exciting creature. Of course your, uh, personal chemistry would prevent you from seeing that. Did it ever occur to you that he might like the girl?

Spock

It occurred. I dismissed it.

McCoy

You would.
