I very nearly did commentary on this one, because I love these two so much I can't stand it sometimes, but I figured I'd spare you. All I can say is, if there's not a "drinking buddy" scene in the next movie, I will be very sad. (And on a shallow note, Deforest Kelley had really nice arms. Unf.)
All caps by me, except the ones from The Wrath of Khan, which are from TrekCore.
