Bernadette: I heard you tell Halley that story the other night, and I thought it was so sweet that Stuart and I turned it into a book.
Howard: The Frightened Little Astronaut?
Raj: That looks just like you. Look how tiny and scared you look.

Sheldon: Oh, it's from Saul Perlmutter. He sent me a picture.
Amy: Ooh, let me see.
Sheldon: Oh, he arranged the cookies to spell out "thank you."
Amy: Sheldon, that word isn't "thank."

Leonard: So you need these people's support and you're sending them baked goods?
Penny: Yeah, they're pretty smart. Don't you think they're gonna realize it's just a bribe?
Sheldon: No, you'd think, but sometimes brilliant people can be painfully oblivious to social cues.
Penny: Thank you for pointing that out, Sheldon.
Sheldon: Anytime.

Amy: It's for the Nobel Laureates. We need them on our side, but unfortunately, Sheldon-
Penny: No. "Unfortunately, Sheldon" that's all you got to say.

Amy: Do you have any cookie dough?
Penny: Uh, I think so. Let me see. Yeah, we've got, uh, chocolate chip and oatmeal raisin.
Sheldon: Oatmeal raisin? I know at least two things wrong with that cookie.

Penny: Someone texting you?
Leonard: Uh, no, I just met my exercise goal for the day.
Penny: By doing the dishes?
Leonard: Hey, you have your goals, I have mine.
Sheldon: Hello.
Amy: What are you two doing?
Leonard: Mm, just finishing a workout.

Bernadette: Halley was scared and Howard told her the sweetest story about when he was in space and I thought I could turn it into a book for her and Michael.
Stuart: Oh, well, I mean, I am an artist. Uh, if you want, I could do the drawings.
Bernadette: Really? That'd be amazing.
Stuart: Yeah, it'd be fun. And a, a nice change of pace from what I usually draw.
Bernadette: What do you usually draw?
Stuart: Well, good night.

Stuart: Oh, that's cute. Did Halley draw that at preschool?
Bernadette: I drew it.
Stuart: Well, good night.
Bernadette: It's supposed to be an astronaut.
Stuart: And I'm supposed to be living on my own at this age, but here we are.

Amy: So you've alienated everyone we need to help us?
Sheldon: Well, Amy, if I had known that someday we'd need them, I would never have insulted them.
Amy: Well, that doesn't make it better.
Sheldon: Oh. Well, it's also not true.

Amy: Uh, George Smoot's on here.
Sheldon: [hisses] Ugh. We have a history.
Amy: Saul Perlmutter?
Sheldon: Oh!
Amy: What about Kip Thorne?
Sheldon: Well, now that was a misunderstanding. I didn't know he was right behind me.

Amy: Hey, good news. They're inviting several Nobel Laureates to our reception.
Sheldon: Oh, great, like who?
Amy: Uh, Makoto Kobayashi.
Sheldon: Ooh.
Amy: What?
Sheldon: Well, I may have been less than kind to him about his Nobel Prize win.
Amy: Why?
Sheldon: I was jealous, angry and new to Twitter. It was a dangerous combination.
Amy: Okay, so scratch Kobayashi.

Howard: Hey, sweetie, I heard you were afraid of the dark. I know someone else who was afraid of the dark once. Your daddy, when he was in space. And just like you, I was wearing a full diaper.

[Halley crying]
Howard: I'll go talk to her.
Bernadette: I don't know why she's suddenly so afraid of everything.
Howard: Honey, remember, she's my child, too.

Amy: I hate to say it, Sheldon, but I think the audience likes them.
Sheldon: Well, that will all change when Ellen asks them how super-asymmetry explains the cosmological excess of matter over anti-matter and they panic, like Leonard trying to do a pull-up.
Leonard: Hey, what'd I do?
Penny: Not a pull-up.

Bernadette: Why does she even want to have scientists on?
Sheldon: Uh, silly question. Who else will give her audience causal explanations of natural phenomena?
Howard: I love you, honey, but think.
