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.

Sheldon: I started working on this presentation to address specific ethical dilemmas. The laws of robotics, whether torture can be justified, and cloning people for fun and spare parts. But I realized before resolving any of these moral quandaries, the real decision is who gets to decide. Do we put it up for a vote? Does everyone get to decide for themselves? Should it be by committee? Is that committee elected or appointed? You see where I'm going? You probably don't. For the smartest decision, we need the smartest person. Ladies and gentlemen, in the field of scientific ethics, we can't rely on democracy or plutocracy. We need an autocracy, or to be more precise, a "Sheldocracy." [slams fist] [military march plays]
Dr. John Sturgis: Um, I don't think this was the assignment.
Sheldon: Sorry, Dr. Sturgis, I pick the assignments now. Everybody, for next class, I want 500 words on what you can do to further the Sheldocracy. Punishment for typos will be severe.
Dr. John Sturgis: Class dismissed.
Sheldon: Hey, that's my line.
Dr. John Sturgis: No, it isn't.
Sheldon: Why don't you see me after class. Class dismissed.

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

Mary: You understand that some people are going to be intimidated by you, because of how smart you are?
Sheldon: Or maybe they'll recognize my intellect and make me their leader.

President Hagemeyer: I must tell you that Sheldon was very excited to hear that you might be joining us.
Linda: Well, isn't he sweet?
Paige: He's a peach.
Sheldon: All right, I'm here. [to Hagemeyer] Hello. [to Linda] Hello. [coldly to Paige] Hello.
Paige: Hi, Sheldon. I'm so excited for you to show me around campus today.
Sheldon: The only reason I'm doing it is because...
President Hagemeyer: He's excited to do it, I'm excited he's doing it. Are you excited?
Linda: Sure.
President Hagemeyer: Everyone's excited. Yay.
Sheldon: [sighs] Come on, let's go.
Paige: You and me, together again. It just feels right, doesn't it? [Sheldon grumbles]

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.
Georgie: 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]
