[flashback]
Meemaw: Open wide, Moonpie. Here comes the choo choo train. Choo choo. Mmm. Isn't that good? [CHUCKLES] That's Meemaw's famous brisket. Would you like the secret recipe? [GASPS] You promise not to tell anybody? Of course you're not gonna tell anybody. I start with a tablespoon of cumin, and then a cup of brown sugar and-
[present day]
Sheldon: I know the recipe.
George Jr.: What?
Sheldon: She told it to me.
George Jr.: When?
Sheldon: February 14, 1982. I was 23 months old, it was Valentine's Day, and Mom and Dad went out for dinner.

George Jr.: You can really remember when you were that little?
Sheldon: Uh-huh. You were there, too. You were still struggling with potty training.
George Jr.: [CHUCKLING]: I don't think so.
Sheldon: Oh, yes. Meemaw used to call you Mr. Soggy Pants.

Sheldon: Dad, could you please come into the living room?
George Sr.: What for?
Sheldon: My brain did something impressive and I'd like to share it with you.

Sheldon: I know Meemaw's brisket recipe.
George Sr.: What?
Meemaw: No, you don't.
Sheldon: Yes, I do. And in order to bring peace to this family, I'm prepared to make it public.
Meemaw: You're bluffing.
Sheldon: One tablespoon of cumin, one cup of brown sugar, two tablespoons of smoked paprika-
Meemaw: Okay, okay, stop.

Mary: How do you know the recipe, Shelly?
Sheldon: Meemaw told it to me on Valentine's Day, 1982. You were out with Dad seeing Cannonball Run at the dollar theater.

[after flashing back his parents being intimate]
George Sr.: Sheldon, want some?
Sheldon: Uh, no, thank you. I'm not hungry.

Mr. Givens: I have a special treat for y'all today. My dear friend and former college roommate is here from the Johnson Space Center in Houston to talk to us about our space program. And yeah, I know what you're thinking. These guys were roomies. How does one go on to be a-a fancy scientist at NASA, and the other's teaching freshman science at a public high school? Yeah, Sheldon?
Sheldon: I was thinking that.
Mr. Givens: Thank you.

Dr. Hodges: Now, of course, before we can set out to explore the solar system, we've got a few minor problems to overcome. Not the least of which is, every time we launch, it costs the U.S. taxpayers hundreds of millions of dollars. [Sheldon raises his hand]
Mr. Givens: Oh, no, no, no, no.
Dr. Hodges: Yes?
Sheldon: If you want to save money, why don't you land the booster rockets instead of letting them drop in the ocean?
Dr. Hodges: [LAUGHS] That's a cute idea, but, uh, it's not technically possible.
Sheldon: Why not?
Dr. Hodges: Well, it's hard to explain. The math is pretty complicated.
Sheldon: Perhaps I could help you with it.

Sheldon: Dad, can we afford a computer?
George Sr.: You do my taxes. What do you think?
Sheldon: Never mind.

Sheldon: [on the phone] Hello, First National Bank. I'd like to speak with a loan officer. It's regarding a second mortgage on my home. My name is Sheldon Lee Cooper. Sure, I'll hold. Oh, I hate hold music.

Sheldon: [on the phone] Hello. Yes, you can help me, Dorothy Fitzpatrick. I'm interested in taking out a second mortgage. I'm nine years old. Why do you ask? That's called age discrimination, Dorothy, but I'm willing to let it slide. I'm glad you find me cute, but I'm deadly serious. I need funds to buy a computer. No, the house isn't in my name. I'm nine. We've established this. I do prepare the taxes for my parents, and if we tighten our belts, we'll have sufficient equity for the loan.

Mary: Sheldon, who are you talking to?
Sheldon: Dorothy Fitzpatrick.
Mary: Who's Dorothy Fitzpatrick? Is she a new buddy from school?
Sheldon: She's the loan officer at The First National Bank of Medford.
Mary: Why are you talking to her?
Sheldon: Mom, can this wait? I'm trying to negotiate favorable terms. Hello, Dorothy? [Mary hangs up]

Tam: Hey, how come you weren't in math class?
Sheldon: That guy from NASA treated me like a child, and I need to prove him wrong.
Tam: You are a child.
Sheldon: Tread lightly, my friend.

Sheldon: Do you know anybody with a modem? I think Radio Shack has one.
Tam: Why?
Sheldon: I need to access thrust-to-weight ratios from the FTP server at the Johnson Space Center.
Tam: Then what?
Sheldon: Then I show that guy from NASA my work and laugh as he begs for mercy.

Mary: What's the matter, baby? Have a tummy ache?
Sheldon: I think it's an ulcer.
George Sr.: Don't be silly. You must have eaten something.
Sheldon: No. My symptoms are consistent with an ulcer.

Mary: Maybe we should take him to the doctor.
Sheldon: Listen to your wife, ulcers are serious.

Dr. Eberland: Well, I've never seen this in someone so young, but, uh, your son has an ulcer.
Sheldon: Thank you.

Sheldon: I've heard some interesting research about treating ulcers with antimicrobials.

Mary: Sheldon! What are you doing?
Sheldon: I just need a minute. These things are so slow. [to Dr. Eberland] Is this your family? They're lovely.

Sheldon: And here near apogee, we gimbal the engine to exert a torque that executes a pitchover maneuver to flip the rocket by 180 degrees.
Dr. Hodges: Well, that's very impressive. Thank you very much for taking the time-
Sheldon: I'm not done.
Dr. Hodges: Uh, sorry.
