Gary: Oh, I gotta tell ya, making lab furniture has made me rich, but this, this is what I really love.
Dr. John Sturgis: Now, just to be clear, we're looking for a financier, not a partner.
Gary: Oh, yes, no, this is your baby. You guys are the parents, I'm just a wet nurse. Just a wealthy, wealthy wet nurse.
Dr. John Sturgis: What does that mean?
Sheldon: A wet nurse is a woman who suckles another...
Dr. John Sturgis: No, no, I know what it means, I just meant what does he mean?
Gary: Well, I mean I just want to be around the process. Anything you need, I'm your guy.
Sheldon: But I'm still in charge, right?
Gary: Did NASA fake the moon landing?
Sheldon: No.
Gary: See, that's what I thought until about a year ago. Oh, we're gonna have so much fun.

Sheldon: Missy and I broke a lot of rules the other night, and we've received no punishment.
George: [sighs] Buddy, it's been a rough week. We're just glad you're both safe.
Sheldon: But in the absence of a divine being, society's rules are what keeps a person's morality in check.
George: Well, there you go.
Sheldon: No, y-you're not following me. If actions have no repercussions, society breaks down, everything devolves into chaos.
George: You might be overthinking this.
Sheldon: I thought so, too. Then I thought about it, and I'm not.
George: Sheldon, you had one bad night. Just let it go.
Sheldon: But... I did something wrong and I got away with it. That's not okay.
George: Buddy...
Sheldon: Socrates maintained that the man who lies to himself has an enemy living within. He's not even a person. He's just a chaos of selfish desires wrapped in an animal hide.

Sheldon: Unbelievable. It's either cartoons or men in their underwear banging their heads together.
Ricky: You complain a lot.
Sheldon: Excuse me?
Ricky: Seriously, dude, you need to relax.
Sheldon: How can I relax? I'm being held captive in a bacterial playground.

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.

Sheldon: No one will even listen to my ideas. I'm being discriminated against because I'm too young.
Dr. John Sturgis: I'm sorry to hear that.
Sheldon: I can't wait till I'm your age and people treat me with respect and reverence.
Dr. John Sturgis: Sometimes older people get discriminated against, too.
Sheldon: For what? Getting smaller and cuter year after year? Look at you.

Sheldon: Good morning. I'm Sheldon Cooper. Thank you for taking the time to hear my proposal. I have some handouts.
Mr. Anderson: I-I'm sorry, who are you?
Sheldon: Oh, I'm... Sheldon Cooper. I'm here to pitch my idea for a grant computer database.
Mr. Anderson: How old are you?
Sheldon: When you hear my presentation, I believe you'll realize my age is irrelevant.
Mr. Anderson: So there's no adult with you?
Sheldon: Well, my mom drove me here, but I told her to wait in the car.
Mr. Anderson: Is this a joke?
Sheldon: I assure you, it's not. When I make jokes, I follow them with a "bazinga" so it's clear. Like this: "Bazinga."

Dr. John Sturgis: Well, sometimes people assume, because of my age, that I'm out of touch, that I, uh, don't know how to use new technologies, that I, uh... Hold on, there's a third one.
