Quote by River Song

"Spoilers!"

"I'm River Song. Check your records again."

"You can't change history. Well, that's what they always say. But they don't really mean it. You can change it, you just can't acknowledge that you've changed it."

"Hello, sweetie."

"Education opens doors."

"Education opens doors to endless possibilities."

"I ain't got the education you got, bub."

"You can't put a price on history."
