One of my favorite scenes from the movie is the campfire scene. Now, I realize people cringe at "row, row, row, your boat", but I love that whole scene, and I love it specifically for McCoy's "I liked him better before he died" comment right after the song.
It's just a brilliant moment of interplay between the Big Three and a gem in the movie.
“I've noticed that about your people, Doctor. You find it easier to understand the death of one than the death of a million. You speak about the objective hardness of the Vulcan heart, yet how little room there seems to be in yours.” - Spock, The Immunity Syndrome
