Adult Sheldon: I wasn't getting the help I needed, so I turned to the smartest resource I knew.
Dr. John Sturgis: [on the phone] Love is a funny thing. They say, "The heart wants what the heart wants," but I think it should be, "The limbic system wants what the limbic system wants."
Sheldon: Finally, someone's making sense.
Dr. John Sturgis: Well, not to brag, but when it comes to unrequited love, I'm kind of an expert.
Sheldon: Well, when I talk to Paige, all she does is drive me crazy.
Dr. John Sturgis: There's a thin line between affection and aggravation. The Roman poet Catullus said, "I hate and I love and I know not why."
Sheldon: I'm not sure what to make of that.
Dr. John Sturgis: Perhaps it'd be more useful in Latin. "Odi et amo..."

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.

Adult Sheldon: I've never been good at sharing. I had to share a womb...
Missy: [over ultrasound video] Ow.
Sheldon: [over ultrasound video] Ow.
["Rico Suave" by Gerardo playing over headphones]
Adult Sheldon: ...a bedroom...
Missy: ♪ Rico...♪
Adult Sheldon: Even my train room had Georgie's sweaty weight bench in it.
George Jr.: Come on, George. One more. Feel the burn, big boy. Feel the burn.
Adult Sheldon: But when it came to academics, the spotlight was all mine.
President Hagemeyer: Sheldon, having you here has been a real boon to this university.
Adult Sheldon: [spotlight shines on Sheldon] I did love basking in its glow.
President Hagemeyer: So we could really use your help in raising the school's profile even higher.
Sheldon: Of course. My intellect is at your service.
President Hagemeyer: Excellent. There is another young physics prodigy we want you to help us recruit. Her name is Paige Swanson. [electricity crackles]

Sheldon: But you don't need another child prodigy. You've already got me.
President Hagemeyer: And you have been... [scoffs] so great. Just imagine what it'd be like having two of you.
Sheldon: Well, why would you want two of me? I mean, I've heard even one of me is a lot to handle.
President Hagemeyer: Well, you're not afraid of a little competition, are you?
Sheldon: From Paige? Hardly. But I should warn you, she can be very difficult.
President Hagemeyer: Well, luckily I've had some practice with that lately.
Sheldon: And how do you handle it?
President Hagemeyer: Usually I, uh, play to their egos. You know, make them feel like the smartest person in the room.
Sheldon: And they fall for that?
President Hagemeyer: Well... [chuckles] not everyone's as smart as you, Sheldon.

Mary: Well, this time I'm actually gonna get a haircut. I had a little accident.
June: Uh-oh, what happened?
Mary: Well, I was sewing and got to daydreaming...
[flashback to Mary working on the sewing machine before she starts to fantasize:]
[fantasy: Missy, Georgie and George are wearing clothes Mary made:]
Missy: I love it. You can make all my clothes from now on.
George Jr.: I'm-a wear this to the prom.
George Sr.: I was wrong, honey, you really are good at this. Boy, am I dumb.
[reality:]
[sewing machine clacking]
Mary: George! George! Help!
George Sr.: What? What's the matter?
Mary: My hair got tangled in the machine.
George Sr.: So pull it out.
Mary: Don't you think I thought of that?!
George Sr.: Well, what do you want me to do? All right, don't move.
[back:]
Mary: And here we are.
June: Okay. Let's get that hat off and see what we're dealing with.
Mary: I don't want to.
June: Oh, come on. I've been doing this a long time. I promise you I've seen worse. Oh... [chortles] That's not bad at all.
