Quotes from fantasy you've actually used.

What is a quote from a fantasy novel you have actually spoken in conversation?

I found myself doing this the other day with

"[Profanity is]... an arbitrary assignment of negative value to words with no inherent negative value based on outmoded moral strictures" -Travis Deverell (HWFWM #4)

(Edit: the situation was someone asking me how I feel about children being exposed to profanity)

Anyway I was curious if anyone else remembers using a quote they read in some SFF.
