What is the best harry potter quote ever?

'' I....am....NOT...Gay!''

Dumbledore's words from the grave right before launching a massive spell against Rowling.

My favorite comes from "Sorceror's Stone", bu Dumbledore.

"Welcome to a new year at Hogwarts! Before we begin our banquet, i would like to say a few words. And here there are: Nitwit! Blubber! Oddment! Tweak!"

Ron: Spiders... the spiders... they want me to tap-dance. And I don't want to tap-dance!
Harry: You tell those spiders, Ron.
Ron: Yeah, tell them... I'll tell them...

OR

Ron: Who do you think that is?
Hermione: Professor R. J. Lupin.
Ron: Do you know everything?
[to Harry]
Ron: How is it she knows everything?
Hermione: It's on his suitcase, Ronald.
Ron: Oh.

OR

Sirius Black: Sorry about the bite, I reckon that twinges a bit.
Ron: A bit? A bit? You almost tore my leg off!

OR

Hermione: Look at you playing with your cards. Pathetic! We've got final exams coming up soon.
Ron: I'm ready! Ask me any questions.
Hermione: All right, what's the three most crucial ingredients in a Forgetfulness Potion?
Ron: I forgot.
Hermione: And what may I ask do you plan to do if this comes up in the final exam?
Ron: Copy off you?
Hermione: No, you won't! Besides, according to Professor McGonagall, we're to be given special quills bewitched with an anti-cheating spell.
Ron: That's insulting! It's as if they don't trust us!

To be honest, practically anything that involves Ron - he just cracks me up everytime!

Voldemort: Give me the stone!!!

Snape: Potter!!!

voldemort: I CAN TOUCH YOU NOW from the 4th movie.

and while he says that harry is screaming

or when lavender brown ( rons girlfrined) calls him won won.

when mrs weasley shouts NOT MY DAUGHTER YOU *****!! in the last book

when Hermonie calls ron an **** and beats him up in the last book
