Sheldon: Why aren't you also driving Missy to school?
Mary: I thought it might be nice for us to chat.
Sheldon: About Missy? She is a bit much, isn't she?

Mary: Here's a question for you. Do you ever see or hear things that other people can't?
Sheldon: Oh, all the time. Right now, the car antenna is vibrating at the same frequency as the pistons in the motor. It's quite irritating, but you know me I don't complain.
Mary: I meant more like things that aren't actually there.
Sheldon: Ah, isn't that the fundamental question of modern metaphysics? What is actually there? This is fun. Missy should ride with Dad more often.

George Sr.: Hey, Tam. I can't find Sheldon. You know where he is?
Tam: I promised not to say.
George Sr.: Tam!
Tam: Lucky for you I'm weak.
[later, as George finds Sheldon's secret study hall:]
George Sr.: Are you kidding me?
Sheldon: I knew Tam was weak.

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.

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: Did you have tuna for lunch or do you just smell like that all the time?
Clara: What?
Sheldon: Did you have tuna for lunch or do you smell like I heard it.
Clara: I'm just wondering who raised you.
Sheldon: My mother and father, and I suppose my meemaw.
Clara: Well, they don't seem like they're doing a great job.
Sheldon: Tell me about it. It's been quite the week.
Clara: I'm sure I'll regret this, but how so?
Sheldon: Before I tell you the story, how much do you know about the mathematics of robotic communication? That's okay. I'll put it into terms a bus lady can understand. There's a wide range of protocols used for inter-robotic...

Sheldon: I think you all understand why I wanted to show you this.
George Sr.: No.
Sheldon: It's an apology. I was the miners, you were the Horta.
Meemaw: How about just saying, "I'm sorry"?
Sheldon: Wow, you're really not getting this. Let's watch it again.

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.

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: 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.

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.

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.

Sheldon: There's my favorite fire exit. Very well marked.
Mary: Nice.
Sheldon: Ooh. See that little step stool? They didn't have that before I got here.
Mary: Very impressive.
Sheldon: I know. And this is where I take my quantum field theory class. Those are my college classmates. I would tell you their names, but most of them won't make it to Christmas.

Sheldon: Are you going for your baseball tryout?
Missy: Yup.
Sheldon: Will it include a written test?
Missy: No.
Sheldon: Well, just in case, here are some baseball facts that may come in handy. It was invented in the 1830s. The first officially recorded game was in 1846, and that game took place in Hoboken, New Jersey.
Missy: I won't need to know that.
Sheldon: Well, now you do, and you'll never forget it.
Missy: Already gone.

Dale: George, I figure we kind of got off on the wrong foot the other day.
George Sr.: Don't worry about it.
Dale: Well, I do worry about it. I-I'd like to take you out for a beer, if that would be okay.
Sheldon: It appears Meemaw told him about you, too.

Sheldon: Hey, Clark. Today's the day.
Clark: It's in the back. I'll go get it.
George Sr.: What's he getting?
Sheldon: A direct-connect 300 baud modem.
George Sr.: How much?
Sheldon: Don't worry, I'm using my allowance. Plus, Clark gave me a healthy discount for helping with his application to medical school.

Sheldon: Ooh! Someone responded to a theory I posted on the physics bulletin board. He called my work flawed.
Missy: That's rude. Let him know he can't push you around. That's what I did at baseball practice.
Sheldon: I'd rather not resort to name-calling. It usually gets me stuffed somewhere uncomfortable.
Missy: That's in person, where people know you're pathetic and weak.
Sheldon: That's true. This is completely anonymous. I can say whatever I want without fear of physical retaliation. Thanks.
Adult Sheldon: And on that day, my sister created the first Internet flame war.
Sheldon: Ooh, that is as cruel as it is grammatical. And send.

Sheldon: It's just so easy. All you do is type in the Usenet address: "sci dot theory dot physics dot research dot quantum." Press enter, and it comes right up. [modem screeching]
Tam: Careful. In WarGames, Matthew Broderick almost blew up the world.
Sheldon: The only thing I'm gonna be blowing up is this fellow's flimsy argument. That was one of my classic jokes; feel free to laugh. [modem finally stops screeching] See? Like magic.

Missy: Get out, I need to change.
Sheldon: You seem upset.
Missy: I am.
Sheldon: I was right? Good for me.
Missy: Just get out. Wait. You get picked on all the time. How do you deal with it?
Sheldon: Who's picking on you?
Missy: It doesn't matter, just tell me.
Sheldon: I usually start by telling myself how much smarter I am than the person who's picking on me, but that won't work for you.
Missy: Out.

Sheldon: Then Geordi goes missing, but Wesley Crusher has a plan to use neutrinos to locate him, since they'd be visible to Geordi's visor.
George Sr.: Is that so?
Sheldon: It is. I recorded the episode. I'll show it to you tonight.
George Sr.: That's okay. You did such a good job explaining it, I feel like I saw it.
Sheldon: You're still seeing it.
