Amy: Well, I want to see it, but not when I'm in the middle of an experiment.
Colin: Still baby powder!
Sheldon: Boy, he is annoying. Do any of those buttons shock him?

Amy: Look, I'm really excited about our paper, too, but I've got a lot of my own work to catch up on, so let's talk later.
Sheldon: Okay, I'll just say one more thing: lambda calculus. And if that wets your whistle, you know where to find me. Boop.

Howard: He sort of hurt my feelings.
Bernadette: Biceps, hammer, abs. Still in it.
Howard: Why wouldn't he want me to be in his planetarium show?
Bernadette: And it's gone.

Howard: Sorry, it's just the director of the planetarium thought it'd be fun for me to join Raj for one of his shows, and he made it clear that he didn't want me to.
Bernadette: Of course he wouldn't want you to. I mean, think about it. If you were him, would you want to share the stage with a sexy-ass astronaut?
Howard: I don't know. How sexy are we talking?
Bernadette: Oh, you know, tight pants, huge biceps, magic hammer.
Howard: Wait, who are we talk-
Bernadette: Shh, I'm back in it.

Sheldon: The fundamental problem with elementary quantum mechanical formalism is that the Fourier transform extends to minus infinity in time.
Penny: Hey, don't dumb this down for me.

Leonard: Oh, Sheldon. Didn't see you there. What's up?
Penny: Well, uh, he was excited to talk science with Amy, but she was working late, so he decided to come over and share it with me. With me, Leonard. With me.

Leonard: Sheldon, we've talked about this. You can't go around boring other people's wives.
Penny: Yeah. I already got a man for that.
Leonard: Yeah, you do.

Sheldon: It's just, I've just been enjoying my collaboration with Amy, but ever since we got back from our honeymoon, she has so little time.
Leonard: Well, she does have her own job.
Sheldon: Yeah, but it's so dull. Trying to understand how the brain translates the five senses into biochemical information. I'd rather wait in line without my phone.

Penny: Okay, well, Leonard's here now. You can talk science with him.
Leonard: Where you going?
Penny: Oh, that thing you were late for. One of us should really be there.

Howard: I just want to let you know I get why you don't want me to be a part of the planetarium show.
Raj: Oh, great. Thanks for stopping by.
Howard: You don't want to talk about the stars next to an actual astronaut. That would be like doing karaoke with a rock star.
Raj: First of all, I've totally done karaoke with a rock star. Or are you forgetting when the Spin Doctors handed me the mic at the Orange County Fair?

Howard: Listen, I understand you being intimidated, but I can't help that I'm proud of being an astronaut. It's a big deal.
Raj: Oh, it certainly is, but I also happen to be very accomplished in my field.
Howard: Great. So you have no reason to be scared of sharing the spotlight.
Raj: Please. I may be scared of heights and spiders and showing up at a costume party that turns out to be a regular party, but I am not scared of sharing the spotlight with you! [Raj walks out, and then reappears]
Howard: What's happening?
Raj: I just stormed out for dramatic effect. I- Actually, I don't have anywhere to go.

Sheldon: President Siebert, how much do you know about physics?
President Siebert: I'm a physicist.
Sheldon: Huh. I would not have guessed that.
President Siebert: I have a doctorate from Indiana University.
Sheldon: Oh, that makes more sense. Well, don't worry, I'll go slow.
President Siebert: Thank you.

Sheldon: Dr. Fowler and I have been working on a theory of super-asymmetry that could reconcile the lack of observation of supersymmetry in a world still governed by string theory.
President Siebert: Interesting. So you're taking the paradigms of supersymmetry, but removing the limitations of obeying the Poincare algebra.
Sheldon: Well, aren't you just the pride of Bloomington?

President Siebert: What do you want, Sheldon?
Sheldon: Dr. Fowler has found herself distracted by the commitments in her own lab. It would be a great help to both of us if you could free her up from her other projects.
President Siebert: I'm confused.
Sheldon: Yeah, well, there's that Indiana.

President Siebert: This is physics research. Dr. Fowler's a neuroscientist.
Sheldon: Yes, but her insights into the very ways we conceptualize symmetry and asymmetry have been invaluable.
President Siebert: Dr. Cooper-
Sheldon: Look, I know what you're thinking, that "they're newlyweds, how are they gonna keep their hands off of each other?" Let me assure you, we will not engage in workplace coitus. Okay, if I won't put a bagel on my desk, I'm certainly not putting Amy's bare bottom.
