Mary: Shelly, how bad could it be? You started college when you were 11.
Sheldon: Well, it was impressive when I was little and cute. But now that I'm old and cute, it's just not the same thing.
Mary: Well, just 'cause you look older, doesn't mean you're any less special.
Sheldon: Of course. It's your fault.
Mary: What?
Sheldon: Well, you've been saying I'm special my whole life, so now I'm conditioned to expect the world to cater to me instead of taking initiative.
Mary: But you are special, sweetie.
Sheldon: You just can't turn it off, can you?

Sheldon: Missy and I broke a lot of rules the other night, and we've received no punishment.
George: [sighs] Buddy, it's been a rough week. We're just glad you're both safe.
Sheldon: But in the absence of a divine being, society's rules are what keeps a person's morality in check.
George: Well, there you go.
Sheldon: No, y-you're not following me. If actions have no repercussions, society breaks down, everything devolves into chaos.
George: You might be overthinking this.
Sheldon: I thought so, too. Then I thought about it, and I'm not.
George: Sheldon, you had one bad night. Just let it go.
Sheldon: But... I did something wrong and I got away with it. That's not okay.
George: Buddy...
Sheldon: Socrates maintained that the man who lies to himself has an enemy living within. He's not even a person. He's just a chaos of selfish desires wrapped in an animal hide.

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.

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]

Dr. John Sturgis: Actually, Sheldon, I do have some news. I reached out to a colleague who's doing a summer research program at the University of Heidelberg, and I think I can get you in.
Sheldon: Heidelberg, Germany?
Dr. Linkletter: A summer program 5,000 miles away. Only a fool would say no to that.
Sheldon: Well, that would certainly help my grad school applications.
Dr. John Sturgis: Yes, and they're doing exciting work on superstrings.
Sheldon: Fantastisch. That's German for "fantastic."
Dr. Linkletter: Ich helfe dir beim packen. That's German for "I'll help you pack."

Sheldon: Hold on, should I be trying to beef up my grad school applications?
Dr. John Sturgis: The competition is fierce. It takes a lot to stand out.
Sheldon: You're my advisors, why didn't you advise me of this?
[flashback:]
Dr. John Sturgis: Sheldon, if I could offer you some advice...
Sheldon: No thank you.
[flashback:]
Dr. Linkletter: Sheldon, I have a recommendation for you.
Sheldon: I have one for you. Trim your nose hair.
[present:]
Dr. Linkletter: Do you remember that?
Sheldon: I do. It looked like a spider was living up there.

Sheldon: [on the phone] Yes, is this the Columbia summer science honors program? Excellent. My name is Sheldon Cooper, perhaps you've heard of me. Well, now you have. Anyways, it's recently come to my attention that you could be an important step in my career advancement. So, good news, I'm available. Yes, I understand I've missed the deadline, but I'm sure you can make an exception. [emotional] But I'm Sheldon Cooper.
