[In Mary Cooper's living room]
Sheldon: And I don't understand why you're taking her side. By being my girlfriend, she's saying you're a weirdo, too.
Amy: I don't think that's what she's saying.
[Cut to Sheldon and Amy in the apartment kitchen, telling Leonard and Penny the story of their trip]
Sheldon: And?
Amy: That's exactly what she was saying.

Amy: Sheldon, what what are you doing?
Sheldon: Just being the un-socialized eccentric my mother always thought I was.
Mary Cooper: You startin' to see why I didn't go in there?

Bernadette: Howie, it's in poor taste.
Howard: No, it's not. Check it out. He says fun stuff.
Remote Control Stephen Hawking: Hey good lookin', want to go for a spin? (Howard spins the toy around)
Howard: His eyes also light up in the dark.

Sheldon: Amy, I didn't want it to come to this. But you have left me no choice but to employ the most passionate, seductive dance known to man. The flamenco.
*Sheldon dancing*
Amy: For God's sake, you're ridiculous.
*Amy leaves the apartment*
Sheldon: (To Leonard and Penny) You guys are aroused, right?

Sheldon: I can't believe I was surpassed by a geologist. I mean rocks! He studies rocks! If rock is so great, how come paper beats it?

Raj: I have to say, I am happy with your ob-gyn.
Howard: Cool. 'Cause she says you're doing a great job as "weird friend who doesn't have to be at every appointment."

Leonard: How much money did he win?
Raj: Over half a million dollars.
Leonard: Wow.
Howard: And he doesn't have to use it for research, he can do whatever he wants with it.
Sheldon: Oh, good, maybe he can build a nicer bridge to live under.

Howard: Here he comes.
Leonard: Right. Be polite.
Sheldon: I know how to behave.
Howard: Do you?

Raj: Hey, congratulations Bert!
Leonard: Yeah, good for you.
Howard: That's amazing.
Bert: Thanks. I was as surprised as anybody. When they called and told me I won, I didn't believe them.
And then they said, "No, you really won." And then I said, "Cool."
Sheldon: Someone call George R. R. Martin, this guy knows how to finish a story.
Bert: I've gotten pretty good at telling it. Well, see ya.
Sheldon: Some genius. I zinged him with sarcasm, he didn't even notice.
Leonard: I know, and it was the greatest sarcastic quip I've ever heard.
Sheldon: Well, aren't you a peach.

Leonard: Ignore him, he's just cranky because Bert from the geology lab won a big grant.
Penny: Oh, I heard him interviewed on the radio! You know, when they told him he won, he didn't believe it, but then he did believe it. It was so funny.
Sheldon: Who listens to the radio any more?

Amy: What happened?
Sheldon: I tried to let go of anger and threw a rock into my foot!
Leonard: Then he got more angry and kicked the rock with his other foot.
Penny: Wha--? And what happened to you?
Leonard: Oh, I laughed so hard, I burst a blood vessel in my nose.

Sheldon: You know, I just need to keep reminding myself that Bert's success is not my failure.
Penny: (enthusiastically) There you go.
Sheldon: And that men of his large stature are more susceptible to a wide array of life-threatening diseases.
Penny: (unenthusiastically) There you go.

Amy: So, is that a yes?
Sheldon: Not yet. How will I learn if I'm comfortable living with Amy or just comfortable because I'm in my own apartment? Now, if this experiment is going to be valid, I suggest a neutral environment.
Penny: Where would you go?
Sheldon: Well, ideally, an enclosed, self-sustaining biodome in New Mexico. Where we would eat crops fertilized with our own waste.

Amy: You know, it's one thing to be envious, but now you're injuring yourself. It has to stop.
Leonard: Although if you are gonna do it again, please let me know, so I can get it on video.

Raj: What's this button do?
Remote Control Stephen Hawking: Gentlemen, start your wheelchairs.
*Raj stares disapprovingly at Howard*
Howard: You laughed when that guy got hit in the nuts.
Raj: I laughed because the guy was Leonard.
