Howard: So what do you think?
Bernadette: I think if you were in space without a shirt on, you'd die.
Howard: Oh. No, I am wearing a shirt. It's just skintight, so you can see my pecs.
Bernadette: When did you get pecs?
Howard: Yesterday, when I made Stuart add them.

Bernadette: I'm just a wife that is so proud of her husband, and doesn't think that he has anything to be embarrassed about.
Howard: Oh. You're sounding less and less Jewish.

Amy: Hey, we just heard that you're the ones who convinced the Nobel Laureates to come.
Sheldon: Thank you.
Penny: You are welcome.
Leonard: You guys deserve this.
Penny: Yeah, now get out of here, go talk to some smart people.
Leonard: Wait a minute.
Penny: Yeah, sorry. Sometimes I forget you're smart because you're so sexy.
Leonard: I can see that.

President Siebert: Dr. Cooper. Dr. Fowler. I was just telling Professor Arnold how you came up with super-asymmetry at your wedding.
Frances H. Arnold: It's a wonderful story.
Amy: Ha, it really is.
Sheldon: I wouldn't say it was the highlight of the wedding, because I've been told not to for reasons I don't fully understand.

Penny: Uh-oh. I haven't been to a lot of parties like this, but what does a physics rumble look like?
Leonard: Kind of like angry chickens. Hmm. Or-or-or-or like, uh, when-when puppets fight.

Amy: What are you doing?
Sheldon: If they stay, everyone will see that their grasp on super-asymmetry is tenuous at best.
Amy: Oh. That's clever.
Sheldon: Yeah, I don't just know the plurals of things, Amy.

Sheldon: Uh, Dr. Campbell and Pemberton, settle a bet for Dr. Fowler and me? We were just discussing, under what conditions the radiative corrections to super-asymmetry could cause time variation of alpha E.M.?
Amy: I say active galactic nuclei at cosmological distances show a part per million deviation. Dr. Cooper says this has been disproven recently with quasar observations.
Sheldon: What do you think?
Dr. Campbell: I agree with you.
Sheldon: Good answer.

Dr. Pemberton: Hey, uh, if we haven't said it before, we just want to say thank you.
Dr. Campbell: Yeah. We couldn't have proven super-asymmetry without you.
Sheldon: Wait-wait. You all heard them say it. They didn't do anything.
Leonard: Sheldon. Shut up.
Sheldon: Yeah-- Well, that's rude.
Leonard: No. Shut up.
Sheldon: Oh, the code word, thank you.

Howard: "Once upon a time, there was a little astronaut who was sitting in a rocket waiting to go to space. And while all the other astronauts laughed and joked, he stayed quiet, because he had a secret. He was scared. He had another secret, too. He was only pretending to be scared to trick the alien king."
Bernadette: Howie.
Howard: Fine. There was no alien. [chuckles] There was a bossy wife, though. We'll get to her later.
