Uncle Vernon: And Dudley, you will be?
Dudley Dursley: I'll be waiting to open the door.
Uncle Vernon: Excellent. And you?
Harry: I'll be in my bedroom, making no noise and pretending I don't exist.

Let me see; red hair, vacant expressions, tatty second-hand books, you must be the Weasleys.

Lucius Malfoy

Even in the wizarding world, hearing voices isn't a good sign.

Hermione

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.

Hermione: Look. Hagrid's our friend, why don't we just go and ask him about it?
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.

Lucius Malfoy: Let us hope that Mr. Potter will always be around to save the day.
Harry: Don't worry. I will be.

Ron, I should tell you, most Muggles aren't exactly accustomed to seeing a flying car.

Harry

[to invisible Harry and Ron] If, er, anybody was looking for some stuff, then all they have to do is follow the spiders. Yep. That'd lead 'em right. That's all I have to say. Oh, and someone'll need ter feed Fang while I'm away.

Hagrid

Weasley's wand causes devastation with the simplest spells. We'll be sending Potter to the hospital wing in a matchbox.

Professor Snape

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.

Hermione: Look at my face.
Ron: Look at your tail.

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.
