J.K. Rowling, Harry Potter and the Order of the Phoenix

"Did you see me disarm Hermione, Harry?""Only once"said Hermione stung. "I got you loads more then you got me—""I did not only get you once, I got you at least three times—""Well if you're counting the one where you tripped over your own feet and knocked the wand out of my hand—"

"Give her hell from us, Peeves."

"I am not forgotten, you know, no, I still receive a very great deal of fan mail.. . . Gladys Gudgeon writes weekly. . . . I just wish I knew why. . . .”He paused, looking faintly puzzled, then beamed again and returned to his signing with renewed vigor. “I suspect it is simply my good looks. . . ."

"But Dumbledore says he doesn't care what they do as long as they don't take him off the Chocolate Frog cards."

"Indifference and neglect often do much more damage than outright dislike."

"Would you like a cough drop Dolores?"

"You know, Minister, I disagree with Dumbledore on many counts...but you cannot deny he's got style..."

"Don’t put your wand there, boy! ... Better wizards than you have lost buttocks, you know!"

"Things we lose have a way of coming back to us in the end, if not always in the way we expect."

"And anyway, it’s not as though I’ll never see Mum again, is it?"

"By all means continue destroying my possessions. I daresay I have too many."

"You're a prefect? Oh Ronnie! That's everyone in the family!""What are Fred and I? Next door neighbors?"

"Is it true that you shouted at Professor Umbridge?""Yes.""You called her a liar?""Yes.""You told her He Who Must Not Be Named is back?""Yes.""Have a biscuit, Potter."

"Ask us no questions and we’ll tell you no lies."

"Why were you lurking under our window?""Yes - yes, good point, Petunia! What were you doing under our windows, boy?""Listening to the news,"said Harry in a resigned voice.His aunt and uncle exchanged looks of outrage."Listening to the news! Again?""Well, it changes every day, you see,"said Harry."

"Well, we were always going to fail that one,"said Ron gloomily as they ascended the marble staircase. He had just made Harry feel rather better by telling him how he told the examiner in detail about the ugly man with a wart on his nose in the crystal ball, only to look up and realize he had been describing the examiner's reflection."

"Wit beyond measure is a man's greatest treasure."

"Accio Brain!"

"It unscrews the other way."

"Mistletoe,"said Luna dreamily, pointing at a large clump of white berries placed almost over Harry's head. He jumped out from under it. "Good thinking,"said Luna seriously. "It's often infested with nargles."
