Lucius Malfoy: What's the use of being a disgrace to the name of wizard, if they don't even pay you well for it?
Arthur Weasley: We have a very different idea about what disgraces the name of wizard, Malfoy.
Lucius Malfoy: Clearly.
Hermione: Look at my face.
Ron: Look at your tail.
Harry: You're running away? After all that stuff you did in your books?
Gilderoy Lockhart: Books can be misleading...
Harry: You wrote them!
Gilderoy Lockhart: My dear boy, do use your common sense! My books wouldn't have sold half as well if people didn't think *I'd* done all those things!
Harry: Your bird, there was nothing I could do. He just caught fire.
Dumbledore: Oh, and about time too. He's been looking dreadful for days. Pity you had to see him on a burning day.

Ron: Oh, that'd be a cheerful visit. "Ello Hagrid! Tell us, have you been setting anything mad and hairy loose in the castle lately?"
[Hagrid has walked up behind them]
Hagrid: Mad and hairy? Yer wouldn't be talkin' about me, now would ya?
Ron, Hermione, Harry: No.
Harry: You'd better clear out before my bones grow back, or else I might strangle you.
Dobby: Dobby is used to death threats, he gets them five times a day at home.
Even in the wizarding world, hearing voices isn't a good sign.Hermione
