Amy Farrah Fowler: You guys will never believe what just happened.
Rajesh Koothrappali: Yeah, we heard. You did it.
Sheldon Cooper: We did do it.
Amy Farrah Fowler: And we didn't even know we did it!
Howard Wolowitz: Wait, what?
Sheldon Cooper: Two physicists in Chicago had to tell us.
Leonard Hofstadter: Wait, what?
Sheldon Cooper: Their experiment on kaon decay supported our predictions on the higher order corrections pertaining to super-asymmetry.
Penny Hofstadter: Wait, what?
Bernadette Rostenkowski-Wolowitz: Howie, shh.
Howard Wolowitz: What?
Bernadette Rostenkowski-Wolowitz: You can't bad-mouth Anu. They're gonna get back together, and you're gonna look like a jerk. I mean, remember when we broke up, and Penny said all those mean things about you?
Howard Wolowitz: What did she say?
Bernadette Rostenkowski-Wolowitz: I don't want to get into it. Some of it was hurtful, most of it was true.
Howard Wolowitz: Everything okay?
Rajesh Koothrappali: Yeah, it's just Anu's doorbell camera. I helped her install it.
Bernadette Rostenkowski-Wolowitz: You can't look at it. That's spying.
Rajesh Koothrappali: Who the hell is this guy?
Bernadette Rostenkowski-Wolowitz: Ooh, let me see.
(Penny explains to others what not to say infront of Amy and Sheldon to not make them upset...)
Penny Hofstadter: We should just try and avoid anything that makes them think of their project or science or Nobel Prizes or successes or failures.
(Amy and Sheldon walk in...)
Amy Farrah Fowler: What are you guys doing?
Bernadette Rostenkowski-Wolowitz: Nothing.
Sheldon Cooper: Nothing? Like what my career has come to? Thanks a lot.
(Sheldon storms out of the room)
Howard Wolowitz: Nice going.
(Raj is introducing Andrea, the director of the planetarium, to Howard...)
Howard Wolowitz: Nice to meet you. I'm Howard Wolowitz. Engineer, husband, father... astronaut.
Andrea: Really? You're an astronaut?
Howard Wolowitz: Well, I don't like to brag.
Rajesh Koothrappali: Hmm, yeah, but somehow, you manage.
Howard Wolowitz: So, he was your best friend growing up?
Tam Nguyen: Yes.
Howard Wolowitz: Were there no other kids in Texas?
Bernadette Rostenkowski-Wolowitz: Man, that is one hot weather girl.
Howard Wolowitz: How come if I say that I get in trouble?
Bernadette Rostenkowski-Wolowitz: You want to say it? You can say it.
Howard Wolowitz: Nice try. You're gonna have to find some other way to not have sex with me tonight. And it's not weather girl, it's weather woman.
Howard Wolowitz: That was weird, right?
Leonard Hofstadter: Was it? I-I honestly can't tell anymore.
Howard Wolowitz: Higgs had to wait almost 50 years before they built a collider big enough to prove his theory.
Sheldon Cooper: 50 years? But I want to play with it now.
Rajesh Koothrappali: You just have to wait for science to catch up or technology to get cheaper. Think about, uh, DVD players... they used to cost, like, a thousand dollars, but just the other day I used one to smash a bug.
