[Sheldon is throwing laundry in the dryer]
Mary: What am I supposed to do with this?
Meemaw: Send him over to my house before he runs out of gas.

Sheldon: Whoa. That girl just took a book on geostatistics.
Tam: Yeah, so?
Sheldon: That's not required reading for any science course.
Tam: Maybe she wants to squash a spider with it.
Sheldon: No, look, she's reading it. Who is this mystery woman?
Tam: Should we invite her to have lunch with us?
Sheldon: I don't know. So far, it's just been you and me, and we know that works. Do we really want to mess with success?
Tam: We could think of it as an experiment.
Sheldon: Oh, you do know how to push my buttons.

Adult Sheldon: And so, our little social circle grew from two to three. An early example of how people are just drawn to me.

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.

Tam: All right, go ask her.
Sheldon: Why me?
Tam: Your lack of testosterone makes you adorable to women.
Sheldon: I can't argue with that.

Libby: What about you?
Tam: Oh, geology for sure.
Libby: Hmm.
Sheldon: Really? When did you decide that?
Tam: A long time ago. Eat your apple slices. [turns back to Libby and smiles]

Sheldon: Hello.
Libby: Hello.
Sheldon: My name is Sheldon.
Libby: Yeah, you're Sheldon Cooper.
Sheldon: You know who I am?
Libby: Well, there's only one nine-year-old in high school, and you still have your baby teeth.
Sheldon: [to Tam] She knows who I am. It's going well.

Libby: Yeah. Maybe I'll see y'all tomorrow.
Tam: Right. Maybe y'all will.
Sheldon: Bye, Libby. [to Tam] "Y'all"?
Tam: I'm assimilating. Shut up.

Tam: [to Libby] I don't know what's more beautiful, your mind or your eyes.
Sheldon: Tam, please. We're eating.

Sheldon: So why did it take people so long to believe in continental drift, when it's obvious that Africa and South America fit together like a puzzle?
Tam: No, they don't.
Libby: People didn't understand continental drift because they didn't understand sea floor spreading. ... What?
Sheldon: I'm both threatened and delighted by your brain.
Tam: I'm just delighted by it. [looking at a globe] They do fit. That's nuts.

Georgie: How come he gets to tie up the phone and I can't?
Meemaw: Because what is happening in there is called a miracle, and God-fearing people do not get in the way of those.

Sheldon: Thank you.
Libby: Happy to help.
Sheldon: Is there any chance you'd be available to stand guard at 1:45?
Libby: You have a bathroom schedule?
Sheldon: You don't?

Georgie: You missed a spot, weirdo.
Sheldon: I see it.

Mary: All right, I'll make a deal with you.
Sheldon: I'm listening.
Mary: You can go to Houston with your friends, but I want to meet this girl first.
Sheldon: That's very reasonable. Thank you.
Mary: You're welcome.
Sheldon: Now, can you please reach the dryer sheets? I get vertigo on the step stool.

Libby: What are you doing?
Tam: What do you think I'm doing?
Libby: Move your arm before I rip it off.
