Give her hell from us, Peeves. - J.K. Rowling, Harry Potter and the Order of the Phoenix

"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."

"You can laugh! But people used to believe there were no such things as the Blibbering Humdinger or the Crumple-Horned Snorkack!"

"Harry, don't go picking a row with Malfoy, don't forget, he's a prefect now, he could make life difficult for you...""Wow, I wonder what it'd be like to have a difficult life?"said Harry sarcastically."

"Yeah, Quirrell was a great teacher. There was just that minor drawback of him having Lord Voldemort sticking out of the back of his head!"
