Adult Sheldon: While my sister was starting her business, I was trying to save mine.
Sheldon: [on the phone] Hello, this is Sheldon Cooper. May I speak to CEO John Roach, please? It's regarding our stock taking a small dip, and I'd like to hear his game plan. Well, I'm busy, too, but I made the time to call. Fine, may I please speak to your COO? CFO? CTO? Hello?

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.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.

Adult Sheldon: Today I thought we could talk about relationships, so I've invited my lovely wife Amy to help.
Amy: Thanks for letting me join in.
Adult Sheldon: Are you jealous when I do this without you?
Amy: No.
Adult Sheldon: Because one of the most common sources of conflict in relationships is jealousy. Now, Amy, did you know jealousy is triggered in the left part of the cerebral cortex?
Amy: I'm sorry, are you about to explain neuroscience to your wife, the Nobel Prize-winning neuroscientist?
Adult Sheldon: Yes. Jealous?
Amy: I'll tell you when there isn't a microphone in front of us.
Adult Sheldon: Ooh, mystery. That'll keep a relationship on its toes.
Amy: Your bathroom schedule is on the refrigerator. We have no mystery.
Adult Sheldon: Moving on, physical intimacy. I believe I said "physical intimacy," [title card changes] which can pose another challenge in relationships.
Amy: Especially when one partner doesn't want to be intimate as frequently as the other.
Adult Sheldon: Ooh, who are we talking about? [stammers] Don't tell me. Let the mystery continue.
Amy: Just read the next one.

Adult Sheldon: Money is a frequent source of conflict in a relationship.
Amy: Thankfully that's never been a problem for us.
Adult Sheldon: Says the woman who took away my comic book allowance.
Amy: Uh, to start a college fund for our children.
Adult Sheldon: Comic books are an investment.
Amy: There are better places to invest our money than that weird wolf man you like.
Adult Sheldon: His name is Wolverine and you know it.
Amy: Okay we're off on a tangent. I'm taking over. Money can be a source of conflict in a relationship, even having too much.
Adult Sheldon: Wh... Hey, this is my story.
Amy: I know. Jealous?

Missy: I'm gonna bring a bunch to school.
