Professor Ericson: Very well, Mr. Cooper, how do you know you're not just dreaming butterflies can't dream?
Sheldon: Because I'm awake.
Professor Ericson: Or are you dreaming you're awake?
Sheldon: You can see I'm awake and you can hear me talking.
Professor Ericson: Yeah... I don't know. I saw some pretty trippy stuff at a Grateful Dead concert. The drummer turned into a tap-dancing walrus and floated away. So we can't really trust our senses, can we?
Sheldon: We can validate them by comparing them with other observers.
Professor Ericson: Mm, but that would mean we have to hear what they say, which requires... trusting our senses. Do you see a problem with your argument, Mr. Cooper?
Sheldon: I could concentrate better if you weren't flashing your toes at me.

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.

Pastor Jeff: Dear Heavenly Father, as we return to school, we look to your eternal...
Billy Sparks: [stands] I pledge allegiance to the...
Pastor Jeff: Billy, it's not the pledge.

Mary: Hey, Brenda.
Brenda Sparks: She didn't want you to walk her in?
Mary: No. How about Billy?
Brenda Sparks: Oh, I walked him in. Found his homeroom. Explained that "homeroom" is different than his room at home. Still not sure he gets it.
Mary: Tough day.
Brenda Sparks: Yeah.
Mary: You want to get some coffee?
Brenda Sparks: I was thinking vodka, but coffee will do.

Sheldon: Dr. Linkletter.
Dr. Linkletter: Sheldon. How wonderfully early it is to see you. If you've come by for a snack, I picked you up some crackers shaped like fish.
Sheldon: I just wanted to let you know that I don't need you to babysit me. I'm perfectly self-reliant.
Dr. Linkletter: Excellent. I'm not very comfortable around children, even with your level of maturity. How old are you? Six? Seven?
Sheldon: Eleven.
Dr. Linkletter: I see. Then it's good I kept the receipt for this bottle of bubbles shaped like a bear.
Sheldon: I should get going. My philosophy class starts in a few minutes.
Dr. Linkletter: Ah, yes, the great thinkers. Socrates, Plato. Speaking of which, I got you some Play-Doh.
