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?

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.

Mary: Sheldon, faith means believing in something you can't know for sure is real. And right now, I am struggling with that.
Sheldon: So you don't believe in God anymore?
Mary: That isn't something for you to worry about. I need to figure this out myself.
Sheldon: Can I help? Maybe I could provide a fresh perspective.
Mary: I don't think so, baby.
Sheldon: Did you know that if gravity were slightly more powerful, the universe would collapse into a ball?
Mary: I did not.
Sheldon: Also, if gravity were slightly less powerful, the universe would fly apart and there would be no stars or planets.
Mary: Where you going with this, Sheldon?
Sheldon: It's just that gravity is precisely as strong as it needs to be. And if the ratio of the electromagnetic force to the strong force wasn't one percent, life wouldn't exist. What are the odds that would happen all by itself?
Mary: Why are you trying to convince me to believe in God? You don't believe in God.
Sheldon: I don't, but the precision of the universe at least makes it logical to conclude there's a creator.
Mary: Baby, I appreciate what you're trying to do, but logic is here. And my problem is here.
Sheldon: Well, there are 5 billion people on this planet and you're the perfect mom for me. What are the odds of that?

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.
George Jr.: How much you gonna charge for it?
Missy: Nothing. They're my friends.
George Jr.: You think Ronald McDonald let his friends eat for free?
Missy: Ronald McDonald isn't real.
