For a quote I just plain like:
"You read the Bible, Brett? Well there's this passage I got memorized. Ezekiel 25:17? 'The path of the righteous ma is beset on all sides by the inequities of the selfish, and the tyranny of evil men. Blessed is he who in the name of charity and goodwill sheperds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who attempt to poison and destroy my brothers! And you will know my name is the Lord when I rain my vengeance upon thee!'" (Proceeds to murder Brett)

For something insightful:
"In my class, you will learn to think for yourselves again. You will learn to savor words and languages. No matter what anybody tells you, words and ideas can change the world. I see that look in Mr Pitts' eyes like 19th century literature has nothing to do with going to business school or medical school, right? Maybe. You may agree and think yes, we should study our Mr. Pritcher and learn our rhyme and meter and go quietly about the business of achieving other ambitions. Well, I have a secret for you. Huddle Up...Huddle UP! We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion. Medicine, law, business these are all noble pursuits necessary to sustain life. But poetry, beauty, romance, and love; these are what we stay alive for."
