"Just because you've got the emotional range of a teaspoon doesn't mean we all have."
"Twitchy little ferret, aren't you, Malfoy?"
""I hope you're pleased with yourselves. We could all have been killed-or worse, expelled. Now if you don't mind, I'm going to bed."
"Ron," said Hermione in a dignified voice, "you are the most insensitive wart I have ever had the misfortune to meet."
"At least no one on the Gryffindor team had to buy their way in. They got in on pure talent."

"I don't go looking for trouble. Trouble usually finds me."
"Are you insane? Of course I want to leave the Dursleys! Have you got a house? When can I move in?"
"Brilliant! It's Potions last thing on Friday! Snape won't have the time to poison us all!"
"Harry, don't go picking a row with Malfoy, don't forget, he's a prefect now, he could make life difficult for you..."
"Wow, I wonder what it'd be like to have a difficult life?" said Harry sarcastically.
"You can't give a Dementor the old one-two!"
"Proud?" said Harry. "Are you crazy? All those times I could've died, and I didn't manage it? They'll be furious...."
"You know your mother, Malfoy? The expression on her face - like she's got dung under her nose? Is she like that all the time or just because you were with her?"

"Sunshine, daisies, butter mellow, Turn this stupid, fat rat yellow."
"Can I have a look at Uranus, too, Lavender?"
"Percy wouldn't recognize a joke if it danced naked in front of him wearing Dobby's tea-cozy."
"Lockhart'll sign anything if it stands still long enough."
"I tell you, that dragon is the most horrible creature I've ever met, but the way Hagrid goes about it you'd think it was a fluffy little bunny rabbit. When it bit me, he told me off for frightening it. And when I left he was singing it a lullaby."
