Billy Sparks: Well, I'm never asking anybody out again.
George: You will. At least the worst part's over.
Billy Sparks: Doesn't feel like it.
George: Hey. You got rejected, but was it the end of the world?
Billy Sparks: No.
George: And that is extremely valuable information. A lot of guys don't learn that and stop taking chances. And honestly, you dodged a bullet with Missy. The girl is mean.
Billy Sparks: Thanks.

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.

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.
