Sheldon: Mom.
Mary: [wakes up] What is it, Sheldon?
Sheldon: I know you had some questions about Star Trek, so I've compiled a detailed guide outlining all the shows, characters, and how they fit in a timeline.
Mary: Can we do this later? I've got a headache.
Sheldon: Unfortunately not. If we don't do it now, you'll be completely lost when we watch The Animated Series this afternoon.
Mary: Just 20 more minutes.
Sheldon: Mom, this is almost a hundred pages. We have to get started. In the 23rd century, alien races from around the galaxy have come together to form the United Federation of Planets, which is... open your eyes... Headquartered in San Francisco.

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: Since when is it Pancake Sunday?
Mary: Since today.
Sheldon: No, it's not. It's Kellogg's Bran Buds Sunday, like it's been for the past three years.
Mary: Well, I thought it would be fun. I'll- I'll make you any kind of pancake you want.
Sheldon: On Bran Buds Sunday?
Mary: Fine. I'll put Bran Buds in the pancakes.
Sheldon: That could work.
[cut to Mary watching Sheldon eat at the kitchen table:]
Sheldon: [mouth full] It doesn't work. [spits out food]

Mary: Hey, Missy, you awake? [knocks] It's Pancake Sunday.
Missy: [opens door] What's that?
Mary: Well, it's a fun new thing I thought we could... Where are you going?
Missy: I told you. Six Flags with Jamie's family.
Mary: Oh. Well, I could make you pancakes first.
Missy: Pancakes and roller coasters? Do you want me to barf?
Mary: Well, no.

Mandy: Georgie, it's fine. You can flirt with other girls.
Georgie: It doesn't feel like I should.
Mandy: Well, we're not a couple.
Georgie: I know, but we're having a baby together. That ain't nothing.
Mandy: All I'm saying is, you're not tied down.
Georgie: Don't I get a vote in that?
Mandy: Yeah, you get a vote. But we get two votes. You're not tied down.
