If you really think about it ravenclaw is the smartest house. Yes you only here about them because of the triwizard tournament; that just means they do less stupid shit. Grifindor is center of attention because the always do the stupid shit no one else is dumb enough to do, then they get lucky. Slytherin is just stupid in general. And ravenclaw are the the middle child. They think they're smart but no one ever hears or really gibes a shit about them.
Hufflepuff not ravenclaw in the first sentence. Too tired to argue. *facepalm* I took nyquil before my shower. ._.
