George: What do you mean you quit?
Sheldon: It was beneath me.
George: You need to learn there's nothing wrong with a little hard work.
Sheldon: Hard work is calculating neutrino properties to one percent accuracy. Anyone can wash bolts.
George: You begged him for that job.
Sheldon: I assumed he'd realize the value of my intellect and put it to good use.
George: Hang on. You made a commitment. When you say you're gonna do something, you do it.
Sheldon: Well, he could find someone else.
George: Doesn't matter. This is about you being a man of your word.
Adult Sheldon: I wanted to point out that I couldn't be a man of my word, since I hadn't hit puberty, but he seemed pretty grouchy.

George: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

Sheldon: There's going to be a lecture on carbon dating at the Natural Science Museum on Saturday. Who would like to take me?
George: You know what? I'd be happy to.
Meemaw: What happened to helping me at my yard sale?
George: Ooh, is that this Saturday? I'm sorry. I'm taking him to a lecture on, uh what is it? Carbonation?
Sheldon: Carbon dating. A method of determining the age of artifacts and fossils.
George: Hey, we could use that to figure out how old your grandma is.
Sheldon: That won't work. You can't carbon-date something that's alive.
George: Well, then, we'll just chop her down and count the rings.
Meemaw: Oh, George, did my "lump of clay" remark strike a nerve?
George: A little.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.

Georgie: What is this?
Meemaw: That's the exercise guy Meemaw likes.
Georgie: I can't believe anyone pays money to watch old people sweat.
Missy: 40 bucks?
Georgie: They sold over a million of those? At 40 bucks a pop? Do you know how much money that must be?
Missy: I'm not a calculator.
[later:]
Georgie: 40 times... one million. That's 40 million!
Missy: Whoa.

Adult Sheldon: Behind every great scientist, there were often unsung helpers toiling away in the background. Presenting... "Great Lab Assistants in Scientific History" When Alexander Graham Bell needed an assistant, it was Thomas Augustus Watson who answered the call. [laughs] Get it? "The call". [snickers] Madame Curie's daughter Irène was also her lab assistant. Irène was so dedicated, she died of radiation poisoning. Unlike her sister Ève, who selfishly lived to 102. Lastly, Émile Roux was assistant to Louis Pasteur. When they worked on the rabies vaccine, Roux kept a loaded gun in the lab to shoot Pasteur in the head if he got infected. He never had to, but it's fun to know he would have.
Dr. Linkletter: No, Sheldon. You can't be my lab assistant.
Sheldon: Maybe you weren't paying attention. I'll start over. Behind every great scientist, there was a dedicated as...

Adult Sheldon: While not the lab work I hoped to be doing, it did feel good to be part of an actual experiment. A tedious, menial part that could be performed by a monkey. Or worse, an engineer.
