Sheldon: Oh, I don't mind, I'm very good at complaining. If it were an Olympic sport, I'd complain about what a stupid sport it is and then I'd take home the gold.

Leonard: Superman's gone. My stormtrooper's gone.
Sheldon: Your Klingon word-of-the-day calendar's gone.
Leonard: I'd say "damn it" in Klingon, but that wasn't until next month.
Sheldon: It's "khoo-vakh".
Leonard: Khoo-vakh!

Leonard: Sheldon, this is not a big deal. It's a little white lie, everyone does it.
Raj: Not me, I'm a 100% honest in all of my relationships.
Howard: And how single are you right now?
Raj: Eating-cake-on-the-toilet single.

Raj: If we're all gonna die, why am I eating so much kale?

Sheldon: Why would she keep something from me, you know? I shared my body with that woman. And my Netflix password. They recommended "Stella Got Her Groove Back" because of her.

Sheldon: Everybody wants to spend more time with me. I'm like a man made of sugar in a world of ants.

Leonard: Buddy, buddy, listen, nothing bad is going on, she just she just didn't want you to know that the work on her apartment was finished a couple weeks ago.
Sheldon: I don't understand.
Leonard: She's enjoying living with you and she didn't want it to end early.
Sheldon: So, she's deceiving me in order to spend more time with me?
Leonard: Yes.
Sheldon: Oh. Well, I feel both flattered and hurt. Like when people say I look like that skeleton from Nightmare Before Christmas.
Raj: Oh my God, that's who you look like.

Sheldon: So, in the spirit of cohabitation, the theme of today's episode is flags of two regions coming together as one.
Amy: Such as the flag of St. Kitts and Nevis.
Sheldon: So, let's roll up our "sleevis" and get to know Nevis.
*Howard plays a rimshot sound*
Sheldon: Well, I-I like that, but next time check with me.

Penny: So, what's the deal with your apartment? Why's it taking so long?
Amy: Um, it was a drywall problem.
Penny: Oh, no, what happened?
Amy: Well, the drywall got wet, and you do not want wet drywall because when drywall gets wet, it's really more-
Penny: Wet wall?
Amy: Or damp wall, just as bad.
Penny: Mm. So why don't they just get more drywall?
Amy: Well, they went to get some, but the woman at the wall store said it was going on sale and they should wait because the savings-
Penny: Okay, are you done? Bernadette told me your apartment's ready.
Amy: I was done at "wet wall" but you wouldn't let it go.

Amy: It's kind of exciting. I mean we could do whatever we want.
Sheldon: But what if we move and we don't like it? What if there's a smoker in the building? Or pets? Or there could be mold. There could be traffic noise.
*Amy humming the theme from Star Trek*
Sheldon: I'm gonna have to learn a whole new bus route. Are you trying to soothe me by singing the Star Trek theme as a lullaby?
Amy: Yes.
Sheldon: I'm not a child, don't do that.
Amy: Sorry.
Sheldon: Do you know 2001: A Space Odyssey?
*Amy humming "Also sprach Zarathustra*
Sheldon: All right, now that's soothing.

Amy: What's going on?
Sheldon: I'm struggling with the thought of leaving my old bedroom.
Amy: Can it be more of an internal struggle?
Sheldon: I have to see it. While I'm gone, don't breathe on my pillow.
Amy: How about if I just don't breathe at all?
Sheldon: That's my girl.

Amy: What are you doing?
Sheldon: I'm just contemplating Buridan's donkey.
Amy: I understand. I'll leave you be.
Sheldon: What, you're familiar with the reference?
Amy: Of course. Jean Buridan proposed a philosophical thesis stating that a hungry donkey placed between two equidistant bales of hay would be paralyzed by indecision and would starve to death.
Sheldon: Exactly.
Amy: Well, I wouldn't want you to starve to death, so here's an eggplant.
Sheldon: Thank you.
Amy: You know, some people believe that Buridan was plagiarizing Aristotle.
Sheldon: Really?
Amy: Although, in Aristotle's example, he proposed an equally hungry and thirsty man caught between food and drink.
Sheldon: Huh. Yeah, I wonder if that's related to the 12th century Persian philosopher, Al-Ghazali and his story of a man caught between two dates.
Amy: Are you suggesting Al-Ghazali was Aristotelian? 'Cause if anything, he was anti-Aristotelian.
Sheldon: Al-Ghazali was anti-Aristotelian? Boy, you think you know a guy.

Penny: I can't believe I'm saying this, but can we watch the news or something?

Sheldon: Buda and Pest united to form Budapest. And that's why Budapest is the "Budabest".

Leonard: And what's it called when you secretly get rid of all your husband's stuff?
Penny: Wha-That is not true!
Leonard: Bernadette told Howard, Howard told me. Plus, I can see all my stuff is gone!
Penny: Oh, so, you believe your friend, and your friend's wife and your own eyes over me? Wow.
