Well, the text is probably from the books – which I have not read – but I loved this scene in Game of Thrones (Season 3, Episode 9) so much I had to post the dialogue (and watch the scene again on YouTube):
Gilly: How do you know all that?
Samwell: I read about it in a very old book.
Gilly: You know all that from staring at marks on paper?
Gilly: You’re like a wizard.
