Adult Sheldon: I was normally a rule follower, but one of the rules of spring break is to cut loose and break rules.
Sheldon: I'm heading out.
Mary: Where you going?
Sheldon: To see my comic book friends.
George Sr.: Hmm. I'm leaving in a few. You want a ride?
Sheldon: No, I'm taking my bike.
Adult Sheldon: All the way to the bus station. [Sheldon smirks]
George Sr.: Something funny?
Sheldon: Not funny. Just normal.
Adult Sheldon: Smooth.
Sheldon: Bye.
Adult Sheldon: So smooth.

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?

Sheldon: Mom, I know what I want to do for spring break. What happened to your face?
Mr. Lundy: Told you, people take notice.
Mary: This is for my new job.
Sheldon: Is your new job fighting Batman? Because you look like The Joker.

George Sr.: Sales is a tough racket, Mare.
George Jr.: Yeah. It ain't as easy as I make it look.
Mary: Well, I think I'd be good at it.
George Jr.: You sure? Sometimes you got to do a little fibbin'.
Mary: I would do it without that.
George Jr.: And you got to have people skills.
Mary: I have people skills.
George Jr.: Do you?
Mary: I'd like to throw my dinner roll at your head right now, but you don't see me doing it.

Mary: I'm not buying it. I'm thinking about selling it.
George Sr.: You?
Mary: Yes, me. Wouldn't hurt to have extra money.
Sheldon: But you already have two jobs... church and mom.
Mary: Well, that second one doesn't pay much.
Sheldon: I do your taxes. The first one doesn't either.
