Madara: RAPE IS FUN
Itachi: I TOOK WAAAAY TOO MANY DRUGS MAN
Sasuke: I don't have a screw loose... I HAVE NO SCREWS TO LOSE ANYMORE!
Obito: I have exactly zero f**ks to give.
I personally prefer Obito, it fits more with his character and you know what they say. You shouldn't fear the man who goes red in the face, but the man who is stone cold in the face.
