Sheldon: Where are we going?
Missy: Right there.
Sheldon: An old shack in the middle of the woods? Have you even seen Scooby Doo?
Missy: Great, go home.
Sheldon: At night, by myself? Nice try.

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.

Mary: You are right. You have been here longer than me. I don't see why we can't work together.
Peg: That'd be nice.
Mary: Great. So, why don't you go by the bank, and I will drop off the bulletin?
Peg: So no one's gonna answer the phones?
Mary: Fine. You just sit there, and I'll go and do everything.
Peg: Sweet. Oh, today's a stumper. Is "nipto" a word?
Mary: You know what? This is why I was taking charge of everything. Because if I don't, nothing will get done.
Peg: Oh, it's "pinto". [laughs]
Mary: This is exactly what I'm talking about.
Peg: Guess what, Mary. Things were getting done long before you got here.
Mary: I just want everything taken care of for Pastor Jeff.
Peg: Or you just like thinking you're better than everybody.

Pastor Jeff: Isn't he the cutest?
Mary: He sure is.
Peg: Oh.
Pastor Jeff: Yeah, he's an angel. He's just happy all the time... morning, afternoon, middle of the night, 2:00a.m., 3:00a.m., all the a.m.'s, really.
Peg: Dip the pacifier in some whiskey, put him right out. But don't use the good stuff. They can't tell the difference.

Adult Sheldon: Classical physics can predict a lot about the world. For example, it can tell us what happens when one pool ball knocks into another. But when multiple balls careen in different directions, we've entered the wild and woolly world of nonlinear dynamics. And you don't need me to tell you that it's impossible to predict what will happen next. Actually, based on the state of our educational system, you probably do. Now imagine those are people. Even a brilliant young ball who graduated high school at 11 can be caught in the maelstrom. Aah! Our first collision was set in motion when Pastor Jeff and Robin had their baby.
