Darren: Any chance you play Dungeons and Dragons?
Sheldon: And how. I once created a campaign set in 1940s London where Alan Turing was a character, and I had the mathematicians be magic users with theorems instead of spells. The intelligence officers were clerics...
Darren: "Yes" works. We're playing tonight and we're down a magic user. You in?
Sheldon: When are you playing?
Darren: We start at 7:00. We'll go till whenever.
Sheldon: My mom didn't let me stay past 6:00 yesterday. She'll never let me stay till "whenever."
Darren: Bummer.
Sheldon: Mm. You could play at my house.
Darren: No.
Sheldon: Bummer. I've never said that before. Did it sound cool?
Darren: No.
Sheldon: Bummer.

Mary: Shelly, you want ice cream?
Missy: Ice cream!
Sheldon: All right.
Mary: Here you go. And no runnin'.
Sheldon: In these loafers? Not a chance.
Mary: I was jokin'.
Sheldon: Okay.

Mary: Okay, Paige, where should we go to get your backpack?
Paige: The Hello Kitty store.
Sheldon: I would help you find it, but this subpar mall map isn't even oriented north.
Missy: Let's go.
Mary: All right, have fun at the Hello Kitty store, and meet me at the fountain in half an hour.
Sheldon: Just to be clear, there are no actual kitties, right?

Sheldon: This isn't the Hello Kitty store.
Paige: No. It's Hot Topic.
Sheldon: What's the topic, devil worship?
Missy: Hey, did you know there's a bow tie section in the back?
Sheldon: Why would they hide that in the back? [exits]

Sheldon: I don't know. I don't think I should.
Oscar: It's just root beer.
Sheldon: This late in the evening, my mother wouldn't approve.
Oscar: Okay.
Sheldon: Then again, I didn't think they'd let me stay, and they did, so maybe it's fine.
Oscar: I know, why don't you roll for it?
Sheldon: Ooh, good idea. Seventeen. Guess I'll have it.
Darren: We playing?
Sheldon: Hold on. Do you have a coaster?
Darren: Yeah, it's in the china cabinet.
Sheldon: And where would that be?

Sheldon: Sorry again for being distracted earlier.
Dr. Linkletter: And I'm so sorry you got locked out. I don't know how that happened.
Sheldon: My brother got a girl pregnant. My mom wanted me to promise I wouldn't tell, but I never did, so technically, I'm not breaking my word.
Dr. Linkletter: I don't care.
Sheldon: Thank you. But it's a secret, so please don't tell anyone.
Dr. Linkletter: Don't you have somewhere to go?
Sheldon: No.

Meemaw: Moon Pie, I know you don't like to hear this, but there are some things in life that can only be learned in time.
Sheldon: So you must have learned them all, huh?
Meemaw: Get out of my house.

Sheldon: And who says you have to be mature to go to college? I've seen Animal House.
Meemaw: You have?
Sheldon: Well, I've seen the poster. Those people are not college material.

George Jr.: You can't go around hitting people.
Missy: I had to do something.
Sheldon: Me too.
Missy: What did you do?
Sheldon: I ran and told the nearest adult.
George Jr.: I don't want you getting in trouble for me.
Missy: But Danny says you're going to hell.
George Jr.: I'm there now. Promise me.
Missy: Fine.
George Jr.: And I know you ain't hitting nobody.
Sheldon: You are correct, sir.

Sheldon: You might want to pace yourself. Our next rest stop isn't for another... 62 miles.
Dr. Linkletter: If anyone needs to go before that, I've got a trucker's buddy in back.
Sheldon: What's that?
Dr. Linkletter: A bottle you urinate in.
Sheldon: I'm sorry, are we the Donner Party?

Missy: You have a calculator I can borrow?
Sheldon: Yes, but I'm using it.
Missy: No, you're not.
Sheldon: [Sheldon taps his head] Why do you need a calculator?
Missy: I'm trying to figure out what to spend my money on. What are you gonna do with yours?
Sheldon: I'm glad you asked. I'm dipping my toe in the exciting world of the stock market by purchasing three shares of RadioShack.
Missy: Why?
Sheldon: Well, as a shareholder, I'll be partial owner of my very favorite company. See, when companies go public, they sell shares of stock...
Missy: I'll just buy my own calculator.

Adult Sheldon: I'd only been a shareholder for one day and I was already reveling in the giddy thrill in being part owner of a thriving tech company.
Sheldon: [on the phone] Hello, RadioShack. Sheldon Cooper, shareholder. I just wanted to let you know I'm so excited to be part of the team. While I sound young, rest assured, I'm far more intelligent than my age would imply. So if there's anything I can do to help, budgeting, product design, finding a word more impressive than "shack," I'm your man.

Paige: You didn't stay for the Q and A.
Sheldon: I had no Q's, and therefore, needed no A's.

Sheldon: I guess I need to call and let him know what a bonehead mistake he made.
George Sr.: There's probably a nicer way to say it.
Sheldon: Did you hear how massive his neutrinos were? We're well into bonehead territory.
George Sr.: Sheldon, you don't need to be rude to him.
Sheldon: When am I rude?
[flashback to Sheldon watching a Missy combs the hair of her Cabbage Patch Doll:]
Sheldon: Stay a child as long as you can. Adulthood will not be kind to you.
[flashback to Sheldon looking at Meemaw's leg:]
Sheldon: Neat. The veins on your calf look like a road map of Texas.
[flashback to Sheldon at dinner time:]
Sheldon: Did you make this taste bad so Dad would lose weight?
[present:]
Sheldon: Fine. I'll be polite. But I still think we could go to San Antonio using Meemaw's leg.

Paige: So, did you guys get, like, assigned to look after Sheldon or something?
Darren: No, he ended up in the room next door.
Oscar: So we took him in, like a dog.
Paige: Him being so young isn't, like, weird?
Sheldon: I'm basically 50.
Darren: And we're basically 12, so it all works out.

Sheldon: But your idea of a winner-takes-all competition is a good one. We just need to come up with something that is fair to both of us. Ooh. What if we list all the spices in Mom's spice rack alphabetically? I'll go first. Adobo. Black pepper. Cinnamon. Coriander. Cumin.
Missy: We're not playing the spice game.
Sheldon: Dill.
Missy: Urgh!

Paige: You got a roommate?
Sheldon: No, it's a single.
Paige: I have a chaperone. Mona. She's, like, 30. It's the worst.
Sheldon: Why do you need a chaperone?
Paige: Maybe they think I'm, like, some kind of troublemaker.
Sheldon: As the owner of the face you punched, they're right.

Dr. John Sturgis: Well, our conversation about my paper resulted in a very productive couple of days. I completely rewrote the whole thing from scratch.
Sheldon: Exciting. I know credits are usually listed alphabetically, but I'm completely fine with my name going second.
Dr. John Sturgis: Sheldon, I've worked on this paper for years. I'm not putting your name on it at all.
Sheldon: But I helped you.
Dr. John Sturgis: You did, but you didn't cowrite the paper with me.
Sheldon: Is that so?
Dr. John Sturgis: Yes, it is.
Sheldon: Well, this is an outrage. After all the help I've given you, and I don't even get credit?
Dr. John Sturgis: Well, of course you are. You're getting a special thanks in the footnotes.
Sheldon: No one reads the footnotes.
Dr. John Sturgis: I do.
Sheldon: Well, I do, too, but that doesn't mean I want to be in them.
Dr. John Sturgis: Sheldon, that's where people get recognition for helping.
Sheldon: Oh, you mean the help of using my math to convert your hazy series of meanderings into a well-formed scientific thesis?
Dr. John Sturgis: I think you're overstating your contribution.
Sheldon: Well, I think you should be wearing a black ski mask because you're trying to rob me blind.
Dr. John Sturgis: Well, if anyone should be wearing an odd piece of apparel, it should be you wearing a baby bonnet, because that's how you're behaving.
Sheldon: [gasps]
Meemaw: Ready to go?
Sheldon: Very! It's a good thing she showed up, because I do not have a comeback.

Sheldon: [on the phone] What do you mean, he hasn't read my fax? Is he aware I'm a shareholder? Well, where's the next shareholders' meeting? Fort Worth? I could barely get my mom to drive me to church.

Adult Sheldon: My sister had taken a different path with her money.
Sheldon: What is that?
Missy: It's a cotton candy machine.
Sheldon: Why?
Missy: It's a machine that makes free cotton candy.
Sheldon: It's not free, you paid for it.
Missy: Meemaw paid for it. And it's still better than lame stocks.
Sheldon: You're going to end up with a stomachache while I get to be part of America's favorite electronics retailer.
