Sheldon: I was exploring dimensional kinematics.
Georgie: Admit it. He's adopted.
Sheldon: How can I be adopted when I have a twin sister? Think, monkey, think.

Sheldon: I smell ammonia. They must've done a thorough cleaning recently. I like that.

Tam: Is that any good?
Sheldon: I'm afraid not. I failed to make a single friend.
Tam: That sucks. I have a tough time making friends, too.
Sheldon: The worst part is, it was important to my mom.
Tam: My parents pressure me about making friends all the time.
Sheldon: So you understand what I'm going through.

Tam: We were forced to live in a refugee camp, where the only thing we had to eat were pigeons and rats.
Georgie: Ha! That's a job for hot sauce.

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?

Adult Sheldon: Finally, the cooking began. 14 hours of cooking. And basting. And spritzing. And tending to the fire.
George: Oh. Rest, my darling. Rest.

George: I don't want this woman in my house anymore.
Mary: She is my mother.
George: She is the devil.

Sheldon: What do you see?
Georgie: Darkness.
Sheldon: Try harder.
Georgie: Wait. I see Elle Macpherson in a bikini. Ooh, it just fell off.

Meemaw: Ko-Kobayashi Maru. Sounds like something you eat at Benihana's. Have you ever been to one of those? They make you sit with strangers. It's crazy.

Sheldon: I want to understand God. Can you help me?
One: Did you not hear what we just said?
Zero: It's a binary universe.
One: God is yes and no.
Zero: Left and right.
One: On and off.
Zero: Something and nothing.
One: Positive and negative.
Zero: Male and female.
One: Light and dark.
Sheldon: But why is there evil and suffering?
Zero: Well, without evil and suffering, there is no good and happiness.
Sheldon: Oh, sure. Binary.

Georgie: You know that movie E.T.? The kid who finds him, his name is Elliott, which starts with an "E" and ends with a "T". Coincidence? I don't think so.
George: You're gonna live with us forever, aren't you?

Georgie: You know spying on kids is creepy.
George: I wasn't spying on kids, I was s-spying on your brother.
Georgie: Why won't you just go inside?
George: Well, then, it wouldn't be spying, now would it?

Sheldon: Are there any Vietnamese superheroes?
Tam: There's one called Half-Face.
Sheldon: Why?
Tam: The communist government forced him to build bombs, and one blew off half his face.
Sheldon: The left half or the right half?
Tam: The bottom half.
Sheldon: That's an important half.

Missy: How was your chicken?
Sheldon: Not bad. The dish soap gave it a nice lemony flavor.

Mrs. Costello: Um, how about MIT in Boston?
Sheldon: Do they have a strong physics program?
Mrs. Costello: They're more of an engineering school.
Sheldon: Next.
