Sheldon: You claim that the only way to calculate the magnetic field in QCD units is using Maxwell's equations, but you're completely discrediting energy density.
Dr. John Sturgis: But you're still off. By a factor of 3.54.
Sheldon: Which would seem insignificant, but when examined closely, you realize that it's the square root of four times pi.
Dr. John Sturgis: Your point being?
Sheldon: Rationalized and non-rationalized units differ by four times pi. Anyone with a basic knowledge of electric and magnetic fields would know that.
Meemaw: I'm lost. Are we still being civil?

Mary: Mom, can you make the salad?
Meemaw: Sure.
George: Hey, don't put in any of those little tomatoes.
Meemaw: Hey, I don't tell you how to impersonate a lump of clay. You don't tell me how to make a salad.

Meemaw: I know this is hard for everyone. It's certainly hard for me. But no one... is more upset with George's passing than the Lone Star Beer company. That flag is at half-mast. [laughter] On the other hand, there's a lot of cows out there that are breathing a sigh of relief. As the king of brisket has put down his fork and ridden off into the sunset. [laughter] And, uh, I'll tell you something...
Missy: Why are they laughing at Dad?
Georgie: 'Cause they love him.
Meemaw: ...that I always kind of kept to myself, but... I wasn't always a big supporter of George and Mary being an item. As a matter of fact, whenever he came to visit, I would always invite Mary's slutty friend Janice over, hoping to catch his interest. [laughter] Hey, Janice. Thanks for coming. You're a doll. [Dale looks back] Anyway... George only had eyes for Mary. And of course brisket. [laughter] And over the years, he surely earned my respect. He was a good man. [voice breaking] And I will always be proud... to call him my son.

Sheldon: Meemaw? I assume you've read the Surgeon General's report on the dangers of smoking?
Meemaw: I'm gonna wait till they turn it into a movie.

Adult Sheldon: Dr. Sturgis was a wise man. It was a learning opportunity. And when the day comes that I'm wrong, I fully plan to admit it.

George: I may not understand exactly what's going on with you and Dr. Sturgis, but you can't be rude to an adult.
Sheldon: What if they're wrong?
George: Doesn't matter. There are plenty of stupid people in the world, but when they're older than you, you got to show them respect.
Sheldon: I understand, sir. Thank you for your incredibly wise advice.
George: Okay.
Missy: Did you just call Dad stupid without calling him stupid?
Sheldon: Yes.

Ms. Ingram: Today we're gonna work on interior angles of a convex polygon. Georgie, where's your brother?
Georgie: I don't know, do you really want him here?
Ms. Ingram: Convex polygons are polygons...
