passage from Storm of Swords, because it's perfect (spoilers)
"...I am guilty of a more monstrous crime." He took a step toward his father. "I was born. I lived. I am guilty of being a dwarf, I confess it. And no matter how many times my good father forgave me, I have persisted in my infamy."
"This is folly, Tyrion," declared Lord Tywin. "Speak to the matter at hand. You are not on trial for being a dwarf."
"That is where you err, my lord. I have been on trial for being a dwarf my entire life."
"Have you nothing to say in your defense?"
"Nothing but this: I did not do it. Yet now I wish I had." He turned to face the hall, that sea of pale faces. "I wish I had enough poison for you all. You make me sorry that I am not the monster you would have me be, yet there it is. I am innocent, but I will get no justice here..."
