Sheldon: And then he ripped up my paper right in front of me.
Mary: What is this man's problem?
Sheldon: I don't know. He didn't even use a ruler. He just ripped it up, willy-nilly.
Mary: Do you want me to call the school?
Sheldon: No, he was in the Army. I want him to think I'm tough.
Mary: Sure. Well, I'm sorry you had a bad day. How about a little trip to RadioShack?
Sheldon: RadioShack's not gonna make this better. It's also not gonna make it worse, so okay.
Mary: You got it.
Sheldon: Maybe he was just intimidated by my intelligence.
Mary: Or maybe he's an insecure bully taking out his frustrations on a little boy.
Sheldon: I like my version better where I'm intimidating and not a helpless child.
Mary: Okay, he's taking out his frustrations on a powerful and intimidating young man.
Sheldon: That works.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

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.

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.

Adult Sheldon: Engineering has a rich and storied history, dating back to ancient times. Some consider it the single most important field of study... Okay, w-wha... no. Stop. I'm sorry. Howard, I can't do this.
Howard Wolowitz: You asked me to write you an introduction to engineering.
Adult Sheldon: Yes, and if I wanted a comedy routine, I'd have gone to Billy Crystal.
Howard Wolowitz: Just let me read it. [clears throat] Engineering has a rich and storied history dating back to ancient times. Some consider it the single most important field of study known to man, from the wheel to the International Space Station, which I went to.
Adult Sheldon: Honestly, this again?
Howard Wolowitz: Like we don't hear about your Nobel Prize all the time.
Adult Sheldon: It's not my fault people ask about it.
Howard Wolowitz: Because you're always wearing it! You have it on right now.
Adult Sheldon: Look how shiny it is.
Howard Wolowitz: [sighs] Just tell your story.

Howard Wolowitz: Wait, so after all this time, that's your problem with engineering?
Adult Sheldon: Evidently.
Howard Wolowitz: So all the teasing and all the abuse had nothing to do with me?
Adult Sheldon: I'll admit, at first, I had a chip on my shoulder because of that class, but then it was mostly you.
Howard Wolowitz: Unbelievable. When will I learn?
Adult Sheldon: I could give you that answer, but if you figure it out for yourself, it'll mean so much more.
Howard Wolowitz: Goodbye, Sheldon.
Adult Sheldon: Bye.

June: I got to admit, I'm a little jealous.
Meemaw: Of what?
June: You.
Meemaw: Why?
June: You have the Dale I never got. I spent a lot of time polishing that turd, and you get all the benefits.
Meemaw: Hey, I put my time in on that, too.
June: Not as much as me.
Meemaw: When I met him, he was a mess.
June: [laughs] You should've seen where I started.
Meemaw: Well, I think we can both agree, he is one lucky turd.
June: Amen, sister.
