Grace: [Talking about Kristina] Excuse me, but you might consider the possibility that she's actually honestly in touch with something beyond your understanding.
Jane: That would be golf and musical theater of the 30s and 40s.

Grace: Boss?
Lisbon: Hmm?
Grace: I've been here nearly six months now, half a year.
Lisbon: What do you want? Half a cake?
Grace: I want to take the lead on this interview.
Lisbon: [she pauses] Okay.
Grace: Okay?
Lisbon: Yeah, sure.
Grace: Thanks, boss.

Grace: Hey. Aren't you supposed to be in the hospital?
Jane: No.
Grace: Yes, you are.
Jane: They've had enough of me. Officer Powell here was kind enough to give me a ride back.
Grace: Well. Thank you...I guess.

Grace: I don't get it. She actually enjoyed helping him kill. One crazy, evil person I understand, but two? Husband and wife? Marriage is suppose to be a sacred, loving thing.
Jane: Yeah, they were soulmates in their strange own way.

Grace: I don't like it.
Rigsby: Me neither. What's the alternative?
Grace: It's immoral.
Rigsby: I don't know about that. Say your brain gets cooked if you use 'em a lot. Make you infertile, too.
Grace: What are you talking about?
Rigsby: Microwaves. What are you talking about?
Grace: The séance this evening!
Rigsby: We were looking at the microwave!

Grace: I don't think it's right to bet on such things. That's a human being that just died!
Rigsby: No, it's okay. We're in Nevada. Here in California, yeah it'd be wrong. [Crosses over to Nevada side.] But here, Nevada. It's okay to gamble on body parts.

Grace: I say we bring him in anyway for creepiness.
Lisbon: Which should be a criminal offense but it isn't.

Grace: It's gotta be tough.
Lisbon: What?
Grace: I mean, a drunk driver. Isn't that what happened to your mother? [Lisbon stares at her] Sorry. It's not my business.
Lisbon: We don't discuss our personal lives in this unit. It's not useful and it's not professional.

Grace: Mr. Jane, I have a question regarding your previous career path.
Jane: Fire away.
Grace: When you met with other psychics, real psychics, could they tell you were just pretending?
Jane: There's no such thing as real psychics.
Grace: I beg to differ. My cousin Yolanda is a psychic.
Jane: Your cousin is deluded or dishonest or both.
Rigsby: Hey, steady.
Grace: No, no, he's entitled to his opinion. He's wrong, though. She has power. She can communicate with the other side. I've seen her do it myself.
Jane: She let you speak with someone that's gone, someone that you love and still miss very much. You wanted her power to be real so it was.
Rigsby: You're so sure you're right. Science doesn't know everything.
Grace: Five hundred years ago, radio would have seemed like magic. Five hundred years in the future, it could be totally normal to communicate with the other side.
Jane: The other side?...There is no other side...

Grace: What was she thinking? She was so beautiful and he's so creepy.
Rigsby: Yeah, Dr. Rubenstein was hot, too. How does he do it?
Jane: All you need is a basic understanding of the evolutionary psychology of women. Rigorously and fearlessly applied. You get to know what buttons to press.
Lisbon: Like we're toasters?
Grace: Like men don't have buttons, too?
Jane: Men are like toasters. Women...little more like accordions.

Grace: Why do people say "Eureka!" when they do something good?
Cho: It's Greek for bingo.
Grace: Well, Eureka.

Grace: Witchcraft creeps me out.
Rigsby: It doesn't bother me. Nerds in cloaks.
Grace: There's more to it than that.
Rigsby: It's just a silly alternative lifestyle, like Star Trek or yoga.
Grace: I do yoga.

Jane: [He looks Fricke straight in the eyes] Do you know who killed Claire?
Fricke: [Emphatically] No.
Jane: Interesting. He is either a habitual liar telling the truth, or he's an honest man lying.

Jane: [observing Cho] Kid's a natural. Look at him. The Cho. No business like Cho business.

Jane: [talking about the painting] May I borrow it for a while?
Rob: I don't know about that. How do I know I'm going to get it back?
Jane: Let me put it another way. Lend it to me, or Agent Van Pelt here will take you and the painting back to Sacramento and keep you there and ask you mind-numbing questions for hours on end.
