Sorting Hat: Hmm, difficult. VERY difficult. Plenty of courage, I see. Not a bad mind, either. There's talent, oh yes. And a thirst to prove yourself. But where to put you?
Harry: Not Slytherin. Not Slytherin.
Sorting Hat: Not Slytherin, eh? Are you sure? You could be great, you know. It's all here in your head. And Slytherin will help you on the way to greatness, there's no doubt about that. No?
Harry: Please, please. Anything but Slytherin, anything but Slytherin.
Sorting Hat: Well if you're sure, better be... GRYFFINDOR!
