[Missy plays with Sheldon's train whistle]
Sheldon: Great, now I have to throw that out.

[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.

George Jr.: This is really good, Meemaw.
Meemaw: Really good? You're spitting the best brisket in Texas all over the damn table.
Mary: Close your mouth when you eat.
Sheldon: Or aim your face the other way.

Meemaw: I tell you what. You go get a piece of paper and a pencil, I'll write it down for you.
George Sr.: Okay. It's happening!
Mary: That's the fastest I've seen him run.
Sheldon: It's the only time I've seen him run.

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.

Dr. Hodges: Anything else?
Sheldon: Yes. I'd like a glass of water. It's time to take my Zantac.

Dr. Hodges: This is groundbreaking work. Thank you.
Sheldon: And?
Dr. Hodges: And?
Sheldon: I thought you might want to apologize.
Dr. Hodges: Well why?
Sheldon: You tried to shut me up with a patch.
Dr. Hodges: Well, I-I give those to everyone. A-And you have to understand, Sheldon, that while your math is-is theoretically correct, we don't have the technical capability to execute it.
Sheldon: So I'm ahead of my time?
Dr. Hodges: Well it would appear so.
Sheldon: All right, call me when you catch up.

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.

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.

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.

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.
