Sheldon: I also tried to get some uranium and build an atomic engine, but that stuff's hard to find.
Tam: Probably for the best.

Mary: So, Tam, tell us about your family. What brings y'all to Texas?
Tam: Well, after the American War-
George Sr.: You mean the Vietnam War.
Tam: We call it the American War.
George Sr.: Hmm.
Tam: Anyway, after the war, my father was sent to a reeducation camp because he fought on the wrong side.
George Sr.: You mean our side.
Tam: I was trying to be nice.

Sheldon: Mm, no, thank you. I'm not hungry.
Tam: "I'm not hungry." The three words you never hear in Vietnam.

Tam: What's the matter?
Sheldon: I-I don't think I can eat this.
Tam: You want to trade? My mom made me fish soup again. How long do we have to be in this country before I get baloney?

Tam: Hey, I've been looking all over for you. Do you know how popular we are?
Sheldon: We?
Tam: Yeah. I put the word out I was helping you with the football stats. And since I'm Asian, they bought it.

Tam: How's puberty treating you? Because it is knocking me for a loop.

Sheldon: Was Ms. Ingram upset I wasn't in class?
Tam: Actually, she was happy. She even did a little dance.

Tam: You know, sometimes you sound like a super villain.
Sheldon: Silence!
Tam: That'll be more effective after your voice changes.
Sheldon: [SIGHS] [IN DEEP VOICE]: Silence.

Sheldon: Tam, you're Catholic, right?
Tam: Yes.
Sheldon: Explain it to me.
Tam: Explain what?
Sheldon: Well, for starters, who do you pray to?
Tam: I guess, Jesus, God and Mary.
Sheldon: Jesus isn't God?
Tam: No, he's his son. But you do eat him, and drink his blood. Oh, there's also a ghost, but not the scary kind.
Sheldon: Like Casper?
Tam: Exactly.
Sheldon: And how does the pope work?
Tam: Well, the pope lives in Italy. He has a special car, and a big pointy hat. It's a wonderful hat.
Sheldon: And is there anything else I should know about?
Tam: Every once in a while, you have to confess your sins to a priest.
Sheldon: Not me, I don't have any sins.
Tam: Then you have the sin of pride.
Sheldon: Your religion is making me feel bad.
Tam: That's how you know it's working.

Sheldon: Have you ever been in detention?
Tam: No. But I do take the school bus. And that is no party. It's like a mental hospital on wheels.
Sheldon: That's a good use of simile.
Tam: Thanks. Well, I'll see you tomorrow. I hope.

Libby: What about you?
Tam: Oh, geology for sure.
Libby: Hmm.
Sheldon: Really? When did you decide that?
Tam: A long time ago. Eat your apple slices. [turns back to Libby and smiles]

Libby: Yeah. Maybe I'll see y'all tomorrow.
Tam: Right. Maybe y'all will.
Sheldon: Bye, Libby. [to Tam] "Y'all"?
Tam: I'm assimilating. Shut up.

Sheldon: So why did it take people so long to believe in continental drift, when it's obvious that Africa and South America fit together like a puzzle?
Tam: No, they don't.
Libby: People didn't understand continental drift because they didn't understand sea floor spreading. ... What?
Sheldon: I'm both threatened and delighted by your brain.
Tam: I'm just delighted by it. [looking at a globe] They do fit. That's nuts.

Mary: You smoke marijuana?
Sheldon: Mom!
Libby: No, ma'am.
Tam: Just say no. [Mary shoots him an unimpressed look]

Sheldon: You know, one of the books mentioned a Vietnamese martial art.
Tam: Vovinam. I'm a blue belt.
Sheldon: Wow.
Tam: Don't be impressed. It's what you get when your mom buys the uniform.
Sheldon: Do you remember any of it?
Tam: I don't even know where the belt is.

Mary: Let's go.
Sheldon: But I came here with Tam.
Mary: Tam, you coming or not?
Tam: I'm good. [to Glenn, after Mary and Sheldon leave] As you can see, I'm not related to them.

Tam: Well, you're in luck. What do you want to know?
Sheldon: I'm being tormented by a sound coming from our refrigerator, and I don't know how to deal with it.
Tam: When my uncle was in a reeducation camp, he would imagine disemboweling his torturers with a bamboo spike.

Sheldon: Maybe I'll just get a book on refrigerator repair instead.
Tam: Okay. New subject. Jessica Gieger wears a black bra. I saw it through the sleeve of her shirt. Not beige, not pink. Black. So mysterious.

Sheldon: Do you think your dad would ever ask you to keep a secret from your mom?
Tam: Oh, no. He's so honest, it's annoying.
Trang Nguyen: Enough talking. Sleep now.
Tam: She's just annoying.

Sheldon: Thank you for letting me sleep in your bed.
Tam: My father taught me that we must always honor our guests and treat them with the utmost courtesy.
Sheldon: The Vietnamese are a very welcoming people.
Tam: Yeah, that hasn't always worked out for us.
