Bernadette: Howie? You doing okay? You've been in there a while.
Howard: (In the bathroom) I'm fine. Be right out.
Am I an American hero? Well, that's a good question, Jim. Dont you think once an astronaut leaves the planet, he's a hero to all the nations of the Earth? (Toilet flush) Okey dokey. I think I have time for one more question.

Amy: Do you realize it took me five years to get a massage from him?
Beverly: Oh, well, that still could be a big step for Sheldon.
Amy: Three minutes. And he used a kitchen timer. I felt like a soft-boiled egg.

Penny: Okay, you know what? This is ridiculous. I've been trying to make a connection with you all day, and clearly I'm getting nowhere.
Beverly: Well, are you seeking a connection or just some form of validation?
Penny: What I was seeking was some sort of friendship. But at this point, I'll take you not insulting me to my face.
Beverly: My intention was never to insult you.
Penny: You've been doing it all day. Do you even know what an insult is?
Beverly: Well, it's not a clinical term. But one example would be your marrying my son, and not inviting me or even telling me the wedding was taking place.
Penny: Okay, good example.

Penny: You really want me to pick up your mother all by myself?
Leonard: Hmm, I just feel like it would be a good chance for you to bond.
Penny: Or a way for you to avoid her?
Leonard: I don't know what he's putting on those cards, but you are smarter than ever.

Sheldon: What about Joss Whedon's work makes you think he'd be okay with rule-breakers and line-cutters?
Guy: The Avengers are rule-breakers. Being vengeful is in their job description.
Sheldon: They work for SHIELD, which is a sanctioned department of the U.S. Government. Do you work for a sanctioned department of the U.S. Government?
Guy: As a matter of fact I do. At a little place called the DMV.
Raj: He's got him there. The D even stands for department.

Penny: You know, she's my mother-in-law. Why can't I bond with her like that?
Bernadette: Amy's with Sheldon, who she loves like a son. You're with her son, who she doesn't.

Sheldon: Excuse me, excuse me, can I please see a show of hands? Who here takes issue with this person cutting the line?
Guy: Told you.
Sheldon: Well, what a sad state of affairs. That you've all been so ground down by life, you don't even notice when someone disrespects you.
Howard: I can't believe we're gonna get beat up, and it's not because of your chair.

Penny: Fine, if you really want me to, I will pick your mom up.
Leonard: Seriously?
Penny: Yeah, you know what, she is my mother-in-law and I'd like for us to have a good relationship.
Leonard: That is very mature of you. So I'm gonna go ahead and say, suckah.

Raj: Did you guys see there's an Avengers screening? Joss Whedon's gonna show some deleted scenes and do a question and answer session.
Sheldon: Oh, well, I have a few questions for him about the last Avengers movie, and a whole lot of answers.

Penny: You really think we made a mistake?
Beverly: At the time I did. But I've never seen Leonard so happy, so perhaps I was wrong.

Sheldon: All right, back to learning.
Penny: Okay.
Sheldon: Oh, easy. Bill Nye the Science Guy.
Penny: Or as I know him?
Sheldon: Creepy old dude from Dancing with the Stars.
Penny: Ding, ding, ding, ding, ding.

Penny: Oh, that's a Venn Diagram, and I remember because I thought to myself, "Venn is he gonna stop talking about this diagram?"

Penny: Hey, listen, what if we have a little mother-in-law, daughter-in-law dinner tonight?
Beverly: So just the two of us?
Penny: Or I invite a few girlfriends, 'cause hearing you say the two of us just sent a chill right down my spine.

Penny: Helium.
Sheldon: Yes.
Penny: Yes.
Sheldon: Taylor Swift.
Penny: Yes. Pi.
Sheldon: Yes. Kardashian.
Penny: More specific.
Sheldon: Khloe?
Penny: Yes.
Sheldon: See, I remembered because if it looks like Kim it's Kim, if it looks kind of like Kim it's Kourtney, and if it looks nothing like Kim it's Khloe.

Penny: Wow. Okay. Well, um, how about this? Maybe while you're still in town, Leonard and I could have another small ceremony. You know, if you're interested.
Beverly: I would find that perfectly acceptable.
Penny: She would find it perfectly acceptable. You guys saw it. We bonded!
