Harry Potter: "Why, what does it mean?" Ron Weasley: "Well, you can't break an Unbreakable Vow..." Harry Potter: "I'd worked that out for myself, funnily enough."
Draco Malfoy: "You'll soon find out that some wizarding families are better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there." Harry Potter: "I think I can tell the wrong sort for myself, thanks."
Rubeus Hagrid: "Ah, go boil yer heads, both of yeh. Harry - yer a wizard."
Draco Malfoy: "No one asked your opinion, you filthy little Mudblood."
Hermione Granger: "Twitchy little ferret, aren't you, Malfoy?"
Draco Malfoy: "Longbottom, if brains were gold you'd be poorer than Weasley, and that's saying something."
Hermione Granger: "Now, if you two don't mind, I'm going to bed before either of you come up with another clever idea to get us killed or worse... expelled." Ron Weasley: "She needs to sort out her priorities." (movie version only)
Ron Weasley: "I don't need help. I know what this means. There's going to be loads of fog tonight. (looking into crystal ball)"
Harry Potter: "I don't go looking for trouble. Trouble usually finds me."
Harry Potter: "Yes." Snape: "Yes, sir." Harry Potter: "There's no need to call me 'sir', Professor."
"Kreacher won't, Kreacher won't, Kreacher won't!" croaked the house elf, quite as loudly as Uncle Vernon, stamping his long gnarled feet and pulling his ears. "Kreacher belongs to Miss Bellatrix, oh, yes, Kreacher belongs to the Blacks, Kreacher wants his new mistress, Kreacher won't go to the Potter brat, Kreacher won't, won't, won't -"
"As you can see, Harry," said Dumbledore, loudly, over Kreacher's continued croaks of "won't, won't, won't", "Kreacher is showing a certain reluctancy to pass into your ownership."
Dobby the House Elf: "Harry Potter, sir!" (before either throwing himself on him or shocking him out of his wits.)
Lord Voldemort: "Greatness inspires envy, envy endangers spite, spite spawns lies. You must know this, Dumbledore." Albus Dumbledore: "You call it 'greatness', what you have been doing, do you?"
Albus Dumbledore: "From here on in Harry, I may be as woefully wrong as Humphrey Belcher, who believed the time was ripe for a cheese cauldron."
Dobby the House Elf: (after doing something that he was not ordered to do or that offends his wizarding family) Bad Dobby! Bad Dobby! BAD DOBBY! (beats himself up)
Mad-Eye Moody: "Oh no you don't!" (transfigures Malfoy into a ferret and makes him do tricks with his wand) Professor McGonagall: "Professor Moody, what are you doing!?" Mad-Eye Moody: "Teaching." Professor McGonagall: "Is that a student?" Mad-Eye Moody: "Technically it's a ferret." Professor McGonagall: Didn't Dumbledore tell you that we never use transfiguration as punishment?" Mad-Eye Moody: "Mighta mentioned it." (Entire quote is movie version only)
Harry Potter:"Nice suit, sir"
Remus Lupin: "Harry, I've left a letter telling your aunt and uncle not to worry -" Harry Potter: "They won't" Remus Lupin: "That you're safe". Harry Potter: "That'll just depress them" Remus Lupin: "And you'll see them next summer", Harry Potter: "Do I have to?"
Dolores Umbridge: Your previous teachers in this subject may have allowed you more licence, but as none of them- with the possible exception of Professor Quirrell, who did at least appear to have restricted himself to age appropriate subjects - would have pased a Ministry inspection-" Harry Potter: "Yeah, Quirrell was a great teacher. There was just that minor drawback him having Lord Voldemort sticking out of the back of his head".
