“Hello, Professor McGonagall,” said Moody calmly, bouncing the ferret still higher.
“What — what are you doing?” said Professor McGonagall, her eyes following the bouncing ferret’s progress through the air.
“Teaching,” said Moody.
“Teach — Moody, is that a student?” shrieked Professor McGonagall, the books spilling out of her arms.
“Yep,” said Moody.
“Moody, we never use Transfiguration as a punishment!” said Professor McGonagall weakly.”

“Yes, Harry Potter!” said Dobby at once, his great eyes shining with excitement. “And if Dobby does it wrong, Dobby will throw himself off the topmost tower, Harry Potter!”

“Well, you can't break an Unbreakable Vow...."
"I'd worked that much out for myself, funnily enough. What happens if you break it, then?"
"You die," said Ron simply. "Fred and George tried to get me to make one when I was about five. I nearly did too, I was holding hands with Fred and everything when Dad found us. He went mental," said Ron, with a reminiscent gleam in his eyes. "Only time I've ever seen Dad as angry as Mum. Fred reckons his left buttock has never been the same since."
“Yeah, well, passing over Fred’s left buttock —”
"I beg your pardon?" said Fred's voice as the twins entered the kitchen.”

“First think of the person who lives in disguise,
Who deals in secrets and tells naught but lies.
Next, tell me what's always the last thing to mend,
The middle of middle and the end of end?
And finally give me the sound often heard
During the search for a hard-to-find word.
Now string them together, and answer me this,
Which creature would you be unwilling to kiss?”
