Harry Potter and the Order of the Phoenix

"Your hand is not up, Miss Granger!"

"The Cruciatus Curse ought to loosen your tongue."

"The Ministry of Magic has always considered the education of young witches and wizards to be of vital importance.The rare gifts with which you were born may come to nothing if not nurtured and honed by careful instruction. The ancient skills unique to the wizarding community must be passed down the generations lest we lose them forever. The treasure trove of magical knowledge amassed by our ancestors must be guarded, replenished and polished by those who have been called to the noble profession of teaching. Every headmaster and headmistress of Hogwarts have brought something new to the weighty task of governing this historic school, and that is as it should be, for without progress there will be stagnation and decay. There again, progress for progress's sake must be discouraged, for our tried and tested traditions often require no tinkering. A balance, then, between old and new, between permanence and change, between tradition and innovation because some changes will be for the better, while others will come, in the fullness of time, to be recognised as errors of judgment. Meanwhile, some old habits will be retained, and rightly so, whereas others, outmoded and outworn, must be abandoned. Let us move forward, then, into a new era of openness, effectiveness and accountability, intent on preserving what ought to be preserved, perfecting what needs to be perfected, and pruning wherever we find practices that ought to be prohibited."

"I will have order!"

"[Voldemort to Dumbledore] “You do not seek to kill me, Dumbledore?" called Voldemort ... "Above such brutality, are you?""

"Give her hell from us, Peeves."

"We thought we heard your moans."

"(Looking into crystal ball) "It’s obvious what this means. There’s going to be loads of fog tonight.""

"“Aaaaah,” said Ron, imitating Professor Trelawney’s mystical whisper, “when two Neptunes appear in the sky, it is a sure sign that a midget in glasses is being born, Harry…”"

"One person can't feel all that at once, they'd explode."

"From now on, I don't care if my tea leaves spell, 'Die, Ron, die,' I'm chucking them in the bin where they belong."

"We've got about as much chance of winning the Quidditch cup this year as dad's got of becoming Minister of Magic.…"

"Hermione, we've been through this before.… We're not going through every exam afterward; it's bad enough doing them once."

"[talking to Zacharias Smith] Here's an idea, why don't you shut your mouth?!"

"You should write a book. Translating mad things girls do so boys can understand them."

"Shut your face."

"It was quite something to hear “O Come, All Ye Faithful” sung by an empty helmet that only knew half the words. Several times, Filch the caretaker had to extract Peeves from inside the armor, where he had taken to hiding, filling in the gaps in the songs with lyrics of his own invention, all of which were very rude."

"Fred and George had made sure no one was likely to forget them any time soon. For a start, they had not left instructions on how to remove the swamp that now filled the corridor on the fifth floor of the east wing. Umbridge and Filch had been observed trying different means of removing it but without success. Eventually the area was roped off and Filch, gnashing his teeth furiously, was given the task of punting students across it to their classrooms. Harry had the strong suspicion teachers like McGonagall and Flitwick could have removed the swamp in an instant, but as in the case of the Wildfire Whizzbangs, they preferred to watch Umbridge struggle."

"Filch prowled the corridors with a horsewhip ready in hand, desperate to catch miscreants, but the problem was that there were now so many of them he never knew which way to turn."

"Not even the users of the Snackboxes could compete with that master of chaos, Peeves, who seemed to have taken Fred's parting words deeply to heart. Cackling madly, he soared through the school, upending tables, bursting out of blackboards, toppling statues and vases; twice he shut Mrs. Norris inside a suit of armour from which she was rescued, yowling loudly, by the furious caretaker. Peeves smashed lanterns and snuffed out candles, juggled burning torches over the heads of screaming students, caused neatly stacked piles of parchment to topple into fires or out of windows; flooded the second floor when he pulled off all the taps in the bathrooms, dropped a bad of tarantulas in the middle of the Great Hall during breakfast and, whenever he fancied a break, spent hours at a time floating along after Umbridge and blowing loud raspberries every time she spoke."

"None of the staff but Filch seemed to be stirring themselves to help [Umbridge]. Indeed, a week after Fred and George's departure, Harry witnessed Professor McGonagall walking right past Peeves, who was determinedly loosening a crystal chandelier, and could have sworn he heard her tell the poltergeist out of the corner of her mouth, 'It unscrews the other way.'"

"[the scars on Harry's hand read:] I must not tell lies and he refers to it when umbridge tell him to tell the centaurs I mean no harm."

"Notes: Harry pointedly refers to these scars in later books when arguing with The Minister of Magic."
