Dr. John Sturgis: Here we go.
Adult Sheldon: For many kids, Christmas morning was the most exciting day of the year. That's only because most kids don't know the joy of getting their college midterms back. It also didn't hurt that Dr. Sturgis looked like an elf.
Dr. John Sturgis: Nice work, Sheldon. Now, you'll notice that your grades are lower than expected. That's because Sheldon did so well, he broke the curve, turning your A's and B's into B's and C's.
Sheldon: They don't seem happy about it. Maybe you can give them candy.

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.

Sheldon: [answering phone] Cooper residence.
Dr. John Sturgis: Hello, Sheldon.
Sheldon: Dr. Sturgis. I'd love to talk to you, but I'm right in the middle of Star Trek: The Next Generation. It's a good one. Geordi goes missing, but Wesley Crusher has a plan to use neutrinos to locate him, since they'd be visible to Geordi's visor.
Dr. John Sturgis: I was actually calling to speak to your father. But I'm glad you're having fun with your friends.
Sheldon: Hang on. I'll go get him. Dad! Phone call!
Adult Sheldon: Even though Dr. Sturgis was confused, one day, Wesley Crusher really would be my friend. Neat, huh?

Mary: Well, if it's everywhere, how can we fight it?
Pastor Jeff: We may not be able to control the world, but we can control our homes. It's up to us to create an environment where the sin of greed can find no purchase.
Mary: Is that what you've done in your home?
Pastor Jeff: Well, I do make my toast vertically, two slices at a time. Take that, Satan.

Sheldon: I have a problem with this permission slip. You didn't cut them in half evenly. Mine has two holes, and Derek here just has one.
Ms. MacElroy: Then trade.
Sheldon: Then Derek will have two holes, and mine will have one.
Ms. MacElroy: You're not going to the water park anyway!
