Well one of my favorite quotes, from "The Catcher in the Rye", uses a curse word and I'm not sure if I can put it up here XD
I like Hamlet. Not so much the story as a whole (it's good but I'm not much one for Shakespeare). I like it because it has some of the greatest lines I've ever heard (er, read):
There is nothing either good or bad, but thinking makes it so.
I could be bounded in a nutshell, and count myself a king of infinite space, were it not that I have bad dreams.
The whole "To Be or Not to Be" speech is awesome, but long XD I'll pick out my favorite part
Devoutly to be wish'd. To die, to sleep; ó
To sleep, perchance to dream: ó ay, there's the rub;
For in that sleep of death what dreams may come,
Hamlet: Denmark's a prison.
Rosencrantz: Then is the world one.
