ANY line spoken by Jar Jar Binks. Also:
From Phantom Menace:
Obi-Wan: But Master Yoda says I should be mindful of the future.
Yoda: Everything! Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering. I sense much fear in you.
C-3PO: I beg your pardon, but what do you mean, "naked?"
C-3PO: My parts are showing? Oh, my goodness, oh!
Shmi Skywalker: There was no father. I carried him, I gave birth, I raised him. I can't explain what happened.
Obi-Wan: Why do I get the feeling that we've picked up another pathetic life form?
Sebulba: You're Bantha poodoo!
any line about Midichlorians
From Attack of the Clones
Anakin: I killed them. I killed them all. They're dead, every single one of them. And not just the men, but the women and the children, too. They're like animals, and I slaughtered them like animals. I HATE THEM.
Obi-Wan: Be mindful of your thoughts Anakin. They'll betray you.
Anakin: It's all Obi-Wan's fault. He's jealous. He's holding me back.
Anakin: Don't be afraid.
Padme: I'm not afraid to die. I've been dying a little bit each day since you came back into my life.
Anakin: What are you talking about?
Padme: I love you.
Anakin: You love me? I thought we had decided not to fall in love. That we'd be forced to live a lie and that it would destroy our lives.
Padme: I think our lives are about to be destroyed anyway. I truly... deeply... love you and before we die I want you to know.
(gag)
Anakin: From the moment I met you, all those years ago, not a day has gone by when I haven't thought of you. And now that I'm with you again... I'm in agony. The closer I get to you, the worse it gets. The thought of not being with you- I can't breath. I'm haunted by the kiss that you should never have given me. My heart is beating... hoping that kiss will not become a scar. You are in my very soul, tormenting me... what can I do?- I will do anything you ask.
Anakin: ... if you are suffering as much as I am, PLEASE, tell me.
Anakin:Just being around her again is... intoxicating.
Anakin: So have you, grown more beautiful... for a senator, I mean
Anakin: One day, I will become the greatest Jedi EVER. I will even learn how to stop people from dying.
Anakin: I don't like sand. It's coarse and rough and irritating and it gets everywhere. Not like here. Here everything is soft and smooth.
