Dr. John Sturgis: Societal norms are different on road trips. Normally, I don't eat junk food, but here, it's tradition. I'm not even sure what a chicharron is.
Sheldon: It's the deep-fried skin of a pig.
Dr. John Sturgis: That seems like something they should say on the bag.

Meemaw: Hello?
Dr. John Sturgis: Did you know that word "hello" wasn't used as a greeting - until the invention of the telephone?
Meemaw: Hi, John.
Dr. John Sturgis: To end a phone call, it was suggested to say, "That is all."
Meemaw: Is that all, John?
Dr. John Sturgis: No, I wanted to invite you to dinner tomorrow night.
Meemaw: Great. Where we going?
Dr. John Sturgis: I can't tell you that. It's a surprise.
Meemaw: You want to give me a clue so I'll know how to dress?
Dr. John Sturgis: Well, dress as if you were going to a Mexican restaurant.
Meemaw: Oh, we're going to Puerta Roja.
Dr. John Sturgis: I can't tell you that, it would ruin the surprise.
Meemaw: John, you do realize that I'll be the one driving us there.
Dr. John Sturgis: Fine, we're going to Puerta Roja, but everything else is a surprise. That is all!

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

George Sr.: Boy, I am stuffed.
Missy: You know, if you're too full to drive, I could help.
George Sr.: You're not driving my truck.
Missy: Come on. Just here in the parking lot?
George Sr.: No.
Missy: Please, Daddy?
George Sr.: I know what you're doing.
Missy: Creating memories that'll last a lifetime?

Adult Sheldon: After a quick burial behind the bar, we were back on the road. Dr. Sturgis tried to find some appropriate music for a proper send-off. Three Christian talk shows and a whole lot of static later, he settled on what he declared the Dixieland jazz of West Texas. ["El Son de la Negra / Guadalajara" playing] Mariachi.
Dr. John Sturgis: Vaya con dios, armadillo. Vaya con dios.

Dr. John Sturgis: I'm doing it. This is going quite well.
Dr. Linkletter: Feel free to pick up the pace. A butterfly just passed us.
Dr. John Sturgis: Well, what's the speed limit?
Sheldon: 75.
Dr. John Sturgis: And I'm going... ten. I'll pick up the pace.
