Can a record run backwards change repaid into diaper?

Nabokov wrote that sentence, not me. I can't even remember which book he wrote it in because, for a while, I was a fiend for his books.

I once actually plagiarized him (unknowingly) only to garner great praise from a professor when asked to contrast and compare "The Epic of Gilgamesh" to the line in Ecclesiastes that goes something like "A live dog is better than a dead lion". It was only years later, upon rereading "Lolita" that I discovered that I did not come up with the description "passionately indifferent".

Anyway....

I was thinking about this tonight and thought to ask all of you about your favorite sentences you've come across in books.

Do any of them come to you out of the blue?

Are there one's you've memorized?

One's you've written down or highlighted so that you don't forget?

One's you refer to?

Another one I seem to always recall is "Sometimes I've believed as many as six impossible things before breakfast" from "Alice Through The Looking Glass"

and my old tag line: "You often learn more by being wrong for the right reasons than you do by being right for the wrong reasons." from "The Phantom Tollbooth".
