Sheldon: So, how does this work with in-laws? Am I supposed to be calling you Dad? Because I don't want to.
Mr. Fowler: You don't have to.
Sheldon: Oh, thanks, Larry. Ooh. That doesn't sound right. Maybe I should pick a vegetable for you.

Howard: What are you guys up to?
Sheldon: Oh, father-in-law, son-in-law bonding. It's going great. Look at what he bought me at the train store. (blows whistle) Yeah, it sounded louder in the car.

Amy: I am not gonna spend weeks in a library looking up old papers. Can't we hire a grad student to do it?
Sheldon: A grad student? I am not trusting our unpublished paper to some millennial. They'll put unicorn emojis on it and then post it on social media.
Amy: Why would they do that?
Sheldon: Economic anxiety, too much avocado toast, who cares?

Amy: But what if we ask one of our friends to help us out? How about Leonard?
Sheldon: Gee, I don't know. Can we trust him?
Amy: He's your best friend in the whole world.
Sheldon: Yes, but he's always struck me as the guy in the plane crash who doesn't wait until you're all the way dead to eat you.
Amy: I think you can trust him.
Sheldon: Oh, Amy, you never lose that childlike innocence.

Sheldon: Well, I don't need you to pretend to be okay for me. If anything, that makes it worse.
Amy: Fine. I'm not okay. We came up with this idea at our wedding. We poured months of our lives into it. I thought we were changing the course of science, and now it's all gone. I'm devastated.
Sheldon: I was wrong, that makes it worse. Go back to being happy.

Leonard: Would you like to say something?
Sheldon: Yes, thank you. I know this is just a scientific theory, but to me, it was more than that. It described the universe in a new and beautiful way. I want that to be the universe we live in, but I guess it's not.

Leonard: It's kind of beautiful, isn't it?
Amy: Yeah, it is.
Sheldon: It's getting kind of close to the curtain.
Leonard: It's in water, it's fine.
Penny: Oh!
Leonard: Oh!
Sheldon: Oh! Looks like we both had theories that were wrong.

Sheldon: It's interesting. I've always thought that my father's journey and my own were so different, but he also faced failure and setbacks. Maybe our lives mirrored each other more than I thought. Maybe our lives mirrored each other more than I thought.

Sheldon: Although, Amy and I did give the world a gift. It would be nice to read some of the thank-you notes.
Leonard: I'm surprised you're interested in some stranger's opinion.
Sheldon: Well, as I always say, a stranger's just a friend who hasn't complimented me yet.

Amy: Okay, here's one from Dr. Saltzberg at UCLA.
Sheldon: Wait, no, stop. I don't want to know. What if he's mean?
Leonard: Well, what if he's complimentary?
Sheldon: I want to know.
Amy: Okay. He says-
Sheldon: I don't want to know.
Leonard: All right, just let me see it. Okay, this is this is really positive. Wow, it's, like, really positive. He says it might be the discovery of the decade.
Amy: He's right. They love it.
Sheldon: This is so exciting. Oh, this may be the Dr. Cooper talking, but pour me another Dr. Cooper.

President Siebert: Welcome to the inner sanctum.
Sheldon: Oh, I do love a good sanctum.

Amy: Okay, I need you to be honest with me. How do I look?
Sheldon: A little shorter, but as we age that happens to all of us.
Amy: Come on, help me out here. I've got a bunch of interviews today.
Sheldon: Well, no one'll notice. They never met you before.

Amy: Do you ever feel guilty that we get to eat in the fancy dining room while our friends have to eat in the regular one?
Sheldon: Yes. Wait, did you say "guilty" or "happy"?
Amy: "Guilty."
Sheldon: Oh, then no. In fact, take a picture of me with the garlic knots to send them.

Amy: We can take you. Come on, Sheldon.
Sheldon: Okay. But I should warn you, we're in a bit of a spat. At least I think we are. Amy, are we still in a spat?
Amy: Are you ready to apologize?
Sheldon: We are.

Leonard: Okay, the cyclops tells you that the enchantress you seek is staying at the Inn of the Dwarven Lords.
Sheldon: Really? An inn? Anu is a concierge at a hotel. That's a little insensitive, don't you think?
Raj: I hadn't noticed that before you mentioned it.
Sheldon: Well, now that I've mentioned it, how do you feel?
Raj: Bad.
Sheldon: Shame on you.
