Sheldon: There's no telling who could buy that house! What if they have dogs? What if they have birds? What if they have both and the birds learned to bark like dogs?
Mary: Sheldon, you're gettin' yourself all worked up.
Sheldon: For good reason... that house is six feet away from my bedroom window. Who knows what kind of smells could jump the gap? Uh, cigarette smoke, a scented candle, a durian?
Mary: What's a durian?
Sheldon: A vile-smelling fruit of the genus Durio.
Mary: When did you smell that?
Sheldon: I haven't, and I'd like to keep it that way.
Mary: It might be nice. It might be a family with kids your age.
Sheldon: I already live with a kid my age... not a fan!

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.

Mary: Mr. Lundy? Come in. What brings you here?
Mr. Lundy: I'm the listing agent on the house next door.
Mary: But I thought you were a teacher and a...
Mr. Lundy: And an actor, yeah, yeah, yeah, yeah, yeah. You've got to get your son out of my open house.
Mary: Why, what's he doin'?
Mr. Lundy: Well...
[flashback montage:]
Sheldon: I noticed there's hair on your coat. Clearly yours is falling out, but do you also have pets?
Sheldon: I detect a hint of garlic. Do you enjoy cooking stinky foods or are you afraid of vampires?
Sheldon: Is there any chance you're just fat?
[present:]
Mary: Oh, dear, I'll go get him.
Mr. Lundy: Thank you. Kind of a dump. But I could sell it.

Meemaw: So what's goin' on?
Missy: I think I have a boyfriend.
Meemaw: Wow.
Missy: But you cannot tell Mom.
Meemaw: Oh, of course... I love not telling your mother stuff.

Meemaw: What's up?
Missy: Can I talk to you about serious woman stuff?
Meemaw: Of course. Is this a... iced tea conversation or a hot tea conversation?
Missy: Definitely hot.
Meemaw: Uh-oh.
