Sheldon: Why would you bring that pecking poop machine into our home?
Missy: To save her life.
Sheldon: What about my life?
Missy: She's not trying to kill you.
Sheldon: Oh, yeah? Then why was there hate in her eyes?
Missy: That's how everybody looks at you.

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.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Adult Sheldon: None of my friends had recorded the episode. I called Tam. I called Dr. Sturgis. Those were all my friends.

Adult Sheldon: Many inventions changed people's lives for the better: the light bulb, the polio vaccine, and one that doesn't get enough credit, the home video cassette recorder. It didn't help keep people out of wheelchairs, but it did keep me from missing Star Trek.

Billy Sparks: Pastor Jeff, do chickens go to heaven?
Pastor Jeff: Well, the Bible doesn't say much about the souls of animals, but I like to believe that God loves all his creatures. Why?
Billy Sparks: My dad wants to eat Matilda.
Brenda Sparks: It's not as bad as it sounds. She stopped laying eggs, so it's off with her head and into the fryer.
Pastor Jeff: Well, I will pray for her little chicken soul.
Brenda Sparks: [chuckles] Just pray she's juicy.
