A Storm of Swords - Tyrion X - “Guilty of Being a Dwarf” Speech
Tyrion stared up at his father's hard green eyes with their flecks of cold bright gold. "Guilty," he said, "so guilty. Is that what you wanted to hear?"
Lord Tywin said nothing. Mace Tyrell nodded. Prince Oberyn looked mildly disappointed. "You admit you poisoned the king?"
"Nothing of the sort," said Tyrion. "Of Joffrey's death I am innocent. 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. You leave me no choice but to appeal to the gods. I demand trial by battle."
