Sheldon: Georgie, why are there bathing suit ladies where Captain Picard should be? Georgie!

Sheldon: Are you still interested in getting rich quick?
Georgie: No, I want to do it slow like a chump.
Sheldon: Oh. Never mind.

Sheldon: Go get me a beer, woman.
Paige: What?
Sheldon: It infuriates my mom when my dad says it.
Paige: Sheldon, stop. You can't upset me.
Sheldon: Why not?
Paige: Because there are things in my life that are way worse than anything that you can come up with.
Sheldon: You mean your parents splitting up.
Paige: Obviously.
Sheldon: I think I know how to irritate you. I bet you think the divorce is all your fault and now your family is torn apart forever. Did I do it? Did I get under your skin? [Paige clenches her first]

Sheldon: Hello, Niblingo. Little nibling.
Mandy: What is it, Sheldon?
Sheldon: I was hoping I could try to calm your baby down.
Mandy: Why?
Sheldon: I'm trying new things to build up a tolerance for setbacks and frustration.
Mandy: So you want to use my child for some kind of experiment?
Sheldon: Yes.
Mandy: Okay, here you go.

[fantasy:]
George: See y'all later.
Mary: 4:00.
Sheldon: Dad, wait.
George: Yeah?
Sheldon: I love you.
George: I love you, too, son.

Mary: Are you gonna go, too? I know you don't believe.
Sheldon: I don't. But I believe in you.
Mary: Thank you.

Sheldon: Well, I'm glad you're enjoying it.
Tam: You're not?
Sheldon: I was touched 82 times this afternoon.
Tam: What do you mean, "touched"?
Sheldon: Not inappropriately. Joyfully. Affectionately. A cheerleader hugged me to her bosom.
Tam: That's amazing. [goes to high five Sheldon]
Sheldon: No more high fives. I can't keep washing my hands.

Sheldon: Greetings from stall number one. As much as I detest that odd-smelling cigarette, I do applaud your rule-breaking bravado. My name is Sheldon. What's yours?

Sheldon: I've been giving geology some more thought.
Tam: Yeah, and?
Sheldon: I've decided it's not really a science.
Tam: It's not?
Sheldon: No, it's more like a hobby. Rock collecting. Childish, really.
Tam: I can see that.

Ms. Hutchins: Aw, honey, you having a hard time adjusting to high school?
Sheldon: I'm having a hard time adjusting to Earth.

Sheldon: I'm not going to be assaulted. High school is a haven for higher learning.
George: Oh, dear God.

Ms. Hutchins: Hey there, Sheldon. What can I get for you today? Chemistry? Quantum mechanics? Astronomy?
Sheldon: No, nothing fun today. I need to learn how to make a friend.

Sheldon: I'm done.
Mary: You finished it?
Sheldon: All of it. Ask me which birds are kosher.
George: I'll bite. Which birds are kosher?
Sheldon: Chickens, yes. Quail, yes. Owls, surprisingly no.
George: Well, there ain't a lot of meat on them anyway.

Dr. Barrett: Do you want to kick this off and tell us exactly what carbon dating is?
Paige: The 5,730-year half-life of carbon 14 is used as a geochronometer.
Dr. Barrett: Anything else you'd like to add?
Sheldon: Um... carbon dating is how we figured out how old my grandmother is.
Adult Sheldon: It was at this moment I learned I was not only brilliant; I was also hilarious. [laughs]

Sheldon: Ooh, this is interesting. According to Socrates, all knowledge exists within the student and just needs to be drawn out through skillful questioning.
Tam: Are you saying I knew that before you even said it?
Sheldon: I don't know, did you?
Tam: Well, according to Socrates, you do know and the answer's inside you.
Sheldon: Well, then, ask me a skillful question to draw it out.
Tam: Do you know if I knew before I knew?
Sheldon: No.
Tam: Hey, it works.
Sheldon: It does.
