Dr. Linkletter: Although I suppose, based on your premise, we could calculate the stress-energy tensor for each.
Adult Sheldon: It turned out their antagonism was the key to their success.
Dr. John Sturgis: ...find an experiment to distinguish them.
Dr. Linkletter: While derivative, I'll admit your point does have some merit.
Dr. John Sturgis: Of course it has merit, you... you...
Sheldon: [whispers] Big, pink Sasquatch?
Dr. John Sturgis: [whispers] Good. [normal voice] You big, pink Sasquatch!

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: Connie, I need to apologize.
Meemaw: Oh, that's okay. Don't worry about it.
Dr. John Sturgis: No, I am worrying about it. I didn't realize that with you and I being in a relationship, me wearing your dead husband's clothes would be emotionally challenging for you.
Meemaw: All right, apology accepted.

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.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George: Talked to Billy.
Missy: Why would you do that?
George: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Sheldon: Dr. Linkletter and I are stuck on a science problem. I know Dr. Sturgis could help, but I'm hesitant to suggest that because I know they have a professional rivalry.
George: Well, the way I see it, y'all are on Team Science, right?
Sheldon: I suppose.
George: And people on the same team don't have to get along to work together.
Sheldon: Like you and Mom.
George: No. A quarterback and his receivers. He doesn't throw it to the guy he likes best. He throws it to the one that's open.
Billy Sparks: So smart.
Sheldon: So, I should ask Dr. Sturgis what he thinks about the dark matter being a Bose condensate?
George: Do you want Team Science to win?
Sheldon: Thank you. This has been helpful. [exits]
Billy Sparks: What's a Bose condensate?
George: I'll tell you at halftime.

Adult Sheldon: You probably think of quantum physics as a white-knuckle rush of adrenaline, like the Peter Pan ride at Disneyland. But the reality can be a little less exciting, especially when you're stuck. [clock ticking] [lights humming] [water bubbles]
Dr. Linkletter: We'll get this.
Sheldon: Perhaps a set of fresh eyes could be helpful.
Dr. Linkletter: If you're going to suggest Dr. Sturgis, I should remind you we have a complicated history.
[flashback:]
Dr. John Sturgis: And your graviton research is mediocre at best!
Dr. Linkletter: You're not qualified to judge my work.
Dr. John Sturgis: All right, that's it. [they shove each other]
[present:]
Sheldon: We'll get this.
