What is a really random Harry Potter quote?

[Amanda]

Here are some

"I don't go looking for trouble. Trouble usually finds me."

"Brilliant! It's Potions last thing on Friday! Snape won't have the time to poison us all!"

"You can't give a Dementor the old one-two!"

"Cut it out," he said firmly, rubbing the scar as the pain receded again. "First sign of madness, talking to your own head," said a sly voice from the empty picture on the wall.

"She's Ron's sister.
But she's ditched Dean!

What if I don't care?
He's your best mate!"

"I'm going to Hagrid's, I've got a good feeling about going to Hagrid's."

"This is night, Diddykins. That's what we call it when it goes all dark like this."

Hope that helps
