"Sorry, i got lost on the road of life."

"The basics of a ninja is to hide yourself well"

"Ninja's aren't supposed to be caught from behind, idiot"

"Ever hear that carelessness can be your worst enemy?"

"A ninja must read beneath the underneath"

"I may have gone too far...." (hehe, i guess you'd have to put that in context ^_^ i love that part)

"Those who don't care for their comrades, are lower than trash"

"Naruto, it's good your releasing the posion.. but you'll die of loss of blood *heart* ... no, seriously"

Zabazu:: Can you see the future?
Kakashi:: Yeah, your going to die.

Kakashi:In the end, those who tasted revenge were not satisfied... it ended in tragedy. You'll only hurt and suffer more... even if you are successful in your revenge, all you'll be left with is emptiness.
Sasuke: What the HELL do you know?!? Don't talk to me like you understand.
Kakashi: Calm down.
Sasuke: What if i were to kill the one you love most? How far would you stray from what you just said? I can make you feel true pain.
Kakashi: That would work, however... unfortunately for me no such person exists. Those people have already been killed.
