Mary: What is going on? Sheldon, are you okay?
Sheldon: My stomach hurts.
Darren: He's gonna throw up.
Mary: Did you give him beer? Did they give you beer?!
[Mary follows Sheldon, Darren and Oscar into the dorm room]
Sheldon: Just root beer.
Mary: It's gonna be okay, baby. [Sheldon throws up] Oh. Why is it so colorful?
Sheldon: Too many... [gags] Skittles. [retches]

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]

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

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.

George Sr.: Where's the coffee?
George Jr.: I finished it.
George Sr.: When you finish a pot, you're supposed to make more.
Mary: Oh, is that the rule?
George Sr.: It is for him. Why are you reading my paper?
George Jr.: Well, pardon me for keeping up on events of the day.
George Sr.: Tomorrow's headline: Father Strangles Son.
George Jr.: Good luck. My horoscope says "things are looking up."

Adult Sheldon: Grown-ups and the elderly had always liked me, and now I had won over undergrads. Like a beloved board game, I'm fun for ages nine to 90.

Mary: You did not just tell our son that he could stay the night by himself.
George Sr.: The campus is safe, and he's not by himself, he's with friends.
Mary: Friends that we don't know. What if there is alcohol?
George Sr.: Then they're gonna get a lot of fun facts about the history of fermented beverages.
Mary: I am serious.
George Sr.: So am I. How else would I know that monkeys get drunk by eating rotten fruit off the jungle floor?
Mary: He is not ready for this kind of situation.
George Sr.: Mary, he's a good kid. He's not gonna drink anything he shouldn't. And if he cared about peer pressure, he wouldn't wear a bow tie.
