"I don't like sand. It's coarse and rough and irritating, and it gets everywhere."
"Impressive... most impressive."
"I find your lack of faith disturbing."
And then, I like this interchange about Anakin:
Former Jedi Padawan Ferus Olin: "Why did he do it?"
Obi-Wan Kenobi, after his exile: "I have my theories, We can't know for certain. I believe Palpatine has been manipulating him for some time. Slowly. Planting seeds. That's the way the Sith operate. And Anakin himself... To have so many gifts, to be the Chosen One... to be so afraid of loss... And to have me as a Master. In the end, there were things between us I hadn't even realized were there. I don't have the answer to why he turned. I can only ask myself that question, over and over again."
