From The End of All Things, by John Scalzi:

Aliens with multiple identified sexes discussing humans:
"Humans generally prefer to not be called 'it' whenever possible."
"The things you learn about people while you're on the job!"

An Alien thinking about earth:
"... from the United Nations, a diplomatic corporation that was not actually the government of the Earth, but which pretended to be for situations like this."

That's some fine stuff, from a dude who gets it.
