Sheldon: Hey, did everybody see there's a sale at RadioShack on nine-volt batteries? It's a golden opportunity to stock up.

Dr. John Sturgis: But we haven't cut open the pineapple yet.
Mary: You boys go ahead. We'll eat the pineapple another time.
Sheldon: But we haven't had a chance to talk about science.
George Sr.: Ooh, can Sheldon come?
Sheldon: Can I?
Mary: No.
Sheldon & John: Aw.

Sheldon: Mom, will Dr. Sturgis be coming over again?
Mary: Oh. Um, I don't know.
Sheldon: He should. We had so much fun talking about the mental hospital, we barely got to talk about science.
Mary: Well, I don't know what his plans are.
Sheldon: Is Meemaw coming for dinner tonight?
Mary: No. She is busy.
Sheldon: With Dr. Sturgis? Maybe I can join them. All my fun facts make me a welcome addition to any dinner date.

Dr. John Sturgis: It's just so wonderful to see you all again.
Mary: We've been looking forward to it.
Sheldon: We sure have. [whispering] One Mississippi, two Mississippi.
Dr. John Sturgis: Uh, why are you counting?
Mary: You know Shelly. He loves his numbers.

Dr. John Sturgis: It's so good to see you.
Sheldon: I don't normally do this, but put her there.
Dr. John Sturgis: No mitten. I'm honored.

Sheldon: Meemaw and Dr. Sturgis are out front. They're walking up the path. They see me. I'm waving. They waved back. They're close to the door. Even closer. Almost there. Door... [doorbell rings] Bell!

Sheldon: The timeline doesn't make sense. I mean, it lists Samwise Gamgee's birth year as both 2963 and 2980.
Ms. Hutchins: Maybe he lied about his age.
Sheldon: Why?
Ms. Hutchins: I don't know. Maybe he thinks his neck makes him look older than he is.
Sheldon: But he's only in his 30s. That's young.
Ms. Hutchins: Thank you.
Sheldon: For a hobbit. For a human, that's mommy-age.
Ms. Hutchins: Thank you.

Mary: Baby, what are you doing?
Sheldon: Working.
Mary: Have you been out here all night?
Sheldon: No. Why, what time is it?
Mary: 7:30.
Sheldon: Oh. Then yes.

Sheldon: I'm so used to thinking about science, I'm not sure how to make myself stop. As soon as I think about not thinking about it, I'm thinking about it.
Meemaw: Well, why don't you just think about something else?
Sheldon: Like what?
Meemaw: I don't know. Read a comic book?
Sheldon: How do you think the spider that bit Peter Parker got radioactive? Science. How do you think Bruce Banner got exposed to gamma rays? Science.
Meemaw: All right.
Sheldon: When the Green Goblin flies-
Meemaw: I said all right.
Sheldon: Science.

Meemaw: Come on, Sheldon. Let's get that blood pumping.
Sheldon: I'd rather not.
Meemaw: Do it. A little exercise will help get your head out of your butt. ... What do you think?
Sheldon: I think I hate this.
Meemaw: Well, you're not thinking about science now, am I right?
Sheldon: I'm thinking about how miserable I am.

Sheldon: [as Gollum] We're never going to figures it out.
Sheldon: [as Smeagol] We can, we're smarts. We're so smarts. Our brains is precious.
Sheldon: [as Gollum] If our brains is precious, we're wasting it on hobbitses. We like sciences.
Sheldon: [as Smeagol] We took a break from sciences. It was making us crazy.
Sheldon: [as Gollum] And look at us now. Look at what those nasty hobbitses have done to us.
Sheldon: [as Smeagol] No, it was physicses. Physicses did this to us.
Sheldon: [as Gollum] Hobbitses.
Sheldon: [as Smeagol] Physicses.
Sheldon: [as Gollum] Hobbitses.
Sheldon: [in bed] Ow!
Missy: I warned you.

Sheldon: I've tried a few different activities, but whatever I do just leads me back to science.
Ms. Hutchins: Well, let's think about it. What's the opposite of science?
Sheldon: Science is based in facts, and the opposite of facts is fiction.
Ms. Hutchins: How about fantasy?
Sheldon: Magic and dragons.
Ms. Hutchins: We have a whole section here.
Sheldon: Ooh, that sounds intellectually bankrupt. I'll give it a shot.

Sheldon: Mom. Mom.
Mary: What's wrong?
Sheldon: I was Gollum and Smeagol and I was in a cave fighting with myself over physics and hobbits. And then I realized that even though physics is frustrating, it won't turn me into a tormented creature who bites the heads off fish. Okay, good night.
George Sr.: [to Mary] I've been doing a great job with Missy. This one's on you.

Meemaw: There are certain grown-up dynamics taking place here that you, you might not be aware of.
Sheldon: Well, I like quantum-chromodynamics and thermodynamics; perhaps I'll like grown-up dynamics. Tell me.
Meemaw: I'm just saying that Dr. Linkletter might be paying special attention to you so he can become better friends with me.
Sheldon: Why?
Meemaw: You're just gonna have to trust me on this one.
Sheldon: Are you saying he doesn't really want me at this lecture?
Meemaw: No, I'm just saying he really wants me at this lecture.
Sheldon: But that's illogical. He knows you're in a relationship with Dr. Sturgis.
Meemaw: And now we're back to it's complicated, so drop it.
Sheldon: I'll try, but dropping things is not where I shine.

Meemaw: We're done talking about this. And I'm not taking you to that lecture!
Sheldon: But I really want to go.
Meemaw: Too bad!
Sheldon: You are incredibly selfish.
Meemaw: Excuse me?
Sheldon: You just care about what you want. You don't care about what I want. You're selfish. How come your eyes stopped blinking?

Meemaw: What, exactly did you say to Dr. Linkletter?
Sheldon: [quietly] I said Hello. This is Sheldon Cooper. I'm speaking quietly because I'm calling from the library. [normally] And he said-
Meemaw: Get to the point.
Sheldon: He's not using me to spend time with you. He said so. You're wrong.
Meemaw: You had no business calling him, Sheldon.
Sheldon: You seem upset. Are you embarrassed because you were wrong?
Meemaw: No.
Sheldon: Are you sure? I would be.
Meemaw: I'm not wrong. He's lying to you, Sheldon.
Sheldon: Interesting. I don't know who to believe.
Meemaw: Really? You're gonna believe some guy you barely know over your own grandmother?
Sheldon: Well, one of them said I'm really smart, and one of them's yelling at me right now.

Dr. Linkletter: [answering phone] Grant Linkletter.
Sheldon: [whispering] This is Sheldon Cooper. I'm speaking quietly because I'm calling from a library.
Dr. Linkletter: [whispering] Hello, Sheldon. Nice to hear from you.
Sheldon: Why are you whispering? Are you in a library?
Dr. Linkletter: Good point. [clears throat, speaks normally:] How can I help you?
Sheldon: My meemaw doesn't want to take me to the lecture because she thinks that you're just using me to spend time with her.
Dr. Linkletter: I see. Well, you're an intelligent young man. What do you think?
Sheldon: I think she's wrong, and you invited me because you know I appreciate the subject matter.
Dr. Linkletter: Exactly right. You're even smarter than I thought.
Sheldon: I knew it. [to Tam] My meemaw couldn't be more wrong.
Kid: Shh!
Sheldon: Oh, like you were reading a book anyway.

Sheldon: That robotics lecture's going to be eye-opening. Get ready to forget everything you know about robot communication.
Meemaw: Moon Pie, I don't know if we're gonna go to this thing.
Sheldon: Why not? We've established that you're free, and I'm a child, so my schedule's wide open.
Meemaw: It's complicated.
Sheldon: Well, we're just sitting here, and we have to talk about something.
Meemaw: Can you just let this one go?
Sheldon: I think we both know the answer to that question.

Meemaw: [to Dr. Linkletter] Can I speak to you for a moment? [to Sheldon] The grown-ups need to talk.
Sheldon: That wasn't made clear.

Dr. Linkletter: Uh, Sheldon, if you're interested, an old friend of mine is giving a lecture next week on the mathematics of robotic communication.
Sheldon: Really?
Dr. Linkletter: Yes. If your grandmother's willing to drive you, maybe we can all go. Make a night of it.
Sheldon: Oh, we'll be there.
Meemaw: Uh-uh-uh, wait, we-we don't even know what night it is.
Dr. Linkletter: Thursday.
Meemaw: Oh. Thursday might be a problem for me.
Sheldon: Thursday's perfect for you.
Dr. Linkletter: Wonderful.
Meemaw: You don't know that.
Sheldon: Yes, I do. Mondays you have bowling, Tuesday's water aerobics, Wednesday, salsa dancing, Fridays, you bring me here. Your Thursday was wide open, but not anymore. We'll see you then.
