Dr. John Sturgis: [answering the phone] Hello?
Sheldon: I'm having a scientific argument with someone and I need your help.
Dr. John Sturgis: I do love a good science fight. Has it devolved to name-calling yet?
Sheldon: Yes. I called him a Pongo pygmaeus.
Dr. John Sturgis: Oh! A Bornean orangutan. That is a creature who would be very bad at science. Well done.
Sheldon: I know.

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.

Adult Sheldon: Thanks to Dr. Sturgis, I had all the intellectual ammunition I needed to bring my opponent to his knees. I accused him of conflating two different interpretations of quantum theory, woefully misrepresenting Paul Dirac, and when I called him a dung beetle in Latin, I was so riled up, I almost started producing testosterone.

George: So how'd you wind up coaching baseball?
Dale: Well, with the sporting goods store, you know, I've sponsored a couple of teams, and then this year, my grandson wanted to play, so it lets me spend more time with him.
George: That's nice. Yeah, I coach my son in football.
Dale: Sheldon?
George: Oh, God, no. Can you imagine?
Dale: You really scared me there for a second.

George: Oh, yeah. Connie's great. You can have a beer with her, watch a football game, joke around. She doesn't mind if you swear. In fact, that woman's got a mouth on her.
Dale: I have noticed that.
George: Yeah. You know, I just realized something. I got more in common with my mother-in-law than I do my own wife.
Dale: That's kind of creepy.
George: Yeah. Let's hope the beer does its job and I don't remember this tomorrow.
