“Every man is wise when attacked by a mad dog; fewer when pursued by a mad woman; only the wisest survive when attacked by a mad notion.”

“A time is coming when men will go mad, and when they see someone who is not mad, they will attack him, saying, 'You are mad; you are not like us.”

“It’s a mad, mad world when your best friend is a dog and your second-best friend is an automatic rifle, but such was life in the Aze.”

“Then when I saw Pain attack Hinata, I was so mad, so full of rage, I let the Nine-Tails take over without even thinking about it.”

“And how do you know that you're mad? "To begin with," said the Cat, "a dog's not mad. You grant that?" I suppose so, said Alice. "Well then," the Cat went on, "you see a dog growls when it's angry, and wags it's tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.”

“You can be as mad as a mad dog at the way things went, you can curse the fates, but when it comes to the end, you have to let go.”
