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: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: Ergo?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

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..."

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]

Brenda Sparks: Hey, Mary.
Mary: Oh, Brenda. Love the haircut.
Brenda Sparks: Thank you. I was always afraid to go short, but I figured I already lost a husband. What's a few inches off the top?
Mary: Well, you look like a new person.
Brenda Sparks: I feel like a new person. I just needed to do something for me. It was either this or get a tattoo on my thigh.
Mary: I think you made the right choice.
Brenda Sparks: Well, I guess. I mean, who's seeing me naked these days?
Mary: Well, I wouldn't know.
