Dr. John Sturgis: Dr. Linkletter is working on an intriguing theory of quantum gravity.
Meemaw: Is that so?
Dr. John Sturgis: He can explain it much better than I can.
Dr. Linkletter: Are you familiar at all with string theory?
Meemaw: Remind me.
Dr. Linkletter: Well, basically, it's a string theoretic interpretation of the graviton.
[flashback:]
Sheldon: Every force is an exchange of particles. Gravity is the exchange of gravitons. Meemaw, are you even listening?
Meemaw: What?
Sheldon: The graviton is a massless string.
[present:]
Meemaw: The graviton is a massless string.
Dr. John Sturgis: Wow!
Dr. Linkletter: Well, yes, it is.
Dr. John Sturgis: When did you learn that?
Meemaw: I get around. In fact, I would go so far as to say that every force is an exchange of particles, and gravity is an exchange of gravitons.
Dr. John Sturgis: Correct!

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.

Dr. John Sturgis: Hello, my little vicuña.
Meemaw: [chuckles] Well, hello to you, too. And more importantly, what is a vicuña?
Dr. John Sturgis: Only what I feel is the cutest camelid on the planet.
Meemaw: Well, I suppose I could ask you what a camelid is, but you're just gonna say more words that I don't know.

Dr. John Sturgis: Connie, I believe I have answers to all your questions.
Meemaw: Lay it on me.
Dr. John Sturgis: Time: the event begins at 6:00 p.m. The dress code is: business attire. Dinner will be served, but it's been suggested that we eat first, because the food is dreadful.
Meemaw: Good to know.
Dr. John Sturgis: And last but not least, a camelid is any member of the camelidae family, such as llamas, alpacas or vicuñas. You didn't ask that one, but, uh, it seemed like something you should know.

Sheldon: Why are you eating cereal for dinner?
Billy Sparks: I was hungry, and my parents are in their bedroom kissing.
