Professor Snape: [taps the blank Marauder's Map with his wand] Reveal your secrets.
[writing appears on the map]
Professor Snape: Read it.
Harry: "Messrs. Mooney, Wormtail, Padfoot, and Prongs, offer their compliments to Professor Snape and..."
Professor Snape: Go on.
Harry: "... and request that he keep his abnormally large nose out of other people's business."

A pity they let the old punishment die... Was a time detention found you hanging by your thumbs in the dungeons... God, I miss the screaming.

Caretaker Argus Filch

Albus Dumbledore: Minister, the evidence of the Dark Lord's return is incontrovertible.
Cornelius Fudge: He's not back!

Why spiders? Why couldn't it be "follow the butterflies"?

Ron

It is not our abilities that show what we truly are... it is our choices.

Dumbledore

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!

Cornelius Fudge: Now write your name only.
Dumbledore: It's quite a long name.

Harry, feel free to treat yourself to a licorice snap. But be careful, they're a wee bit sharp.

Dumbledore

It does not do to dwell on dreams, Harry, and forget to live.

Dumbledore

Dumbledore: A word of caution: dementors are vicious creatures. They will not distinguish between the one they hunt and the one who gets in their way. Therefore I must warn each and every one of you to give them no reason to harm you. It's not in the nature of a dementor to be forgiving. But you know happiness can be found even in the darkest of times, when one only remembers to turn on the light.

Harry: "Come seek us where our voices sound/we cannot sing above the ground...?
Hermione: The Black Lake, that's obvious.
Harry: "An hour long you'll have to look...?
Hermione: Again, obvious. Though admittedly potentially problematic...
Harry: "Potentially problematic"? When was the last time that you had to hold your breath underwater for an hour, Hermione?

Dolores Umbridge: [as the centaurs are taking Umbridge away] Please, tell them I mean no harm.
Harry Potter: Sorry, Professor, but I must not tell lies.
