Penny: We wouldn't even sit in your spot while you're gone.
Sheldon: You're darn right, you wouldn't. No matter where I am, this will always be my spot. Like an embassy in a foreign country, this seat is the sovereign soil of my bottom.

Penny: Do they know why the pipes burst?
Amy: They didn't say.
Leonard: Buildings that have a combination of copper and galvanized steel are susceptible to pinholes and corrosion caused by the mobility of ions in the water. Can't have your head shoved in a toilet as much as I did and not pick up a few things about plumbing.

Penny: The new neighbors are weird.

Leonard: Never leave a belt on the floor. At night, they look like snakes.

Amy: Listen, you and I are gonna be sharing a bed. You know, this is uncharted territory for both of us. How are you feeling about that?
Sheldon: Oh, excited, concerned, a little scared. All the same emotions I feel in line at Space Mountain.

Amy: Sheldon, I understand your apprehension, but let me appeal to the scientist in you. Given the five-week end-date, isn't it the perfect opportunity to consider this an experiment and collect data on our compatibility?
Sheldon: Don't try luring me in with sexy talk.

Sheldon: No matter where I am, this will always be my spot.

Penny: You can stay in Leonard's room, and we'll stay at my place.
Amy: You're sure that's not an inconvenience?
Penny: No, not at all.
Leonard: And we live with Sheldon, so the word "inconvenience" has really lost all meaning.

Amy: Comfy?
Sheldon: Oh, I'm just happy I don't know what this memory foam remembers.

Raj: I'm the son of a gynecologist. I could be helpful.
Bernadette: It would help if you stopped telling me I have a textbook cervix.
Raj: The polite response is, "Thank you for noticing."

Bernadette: This is ridiculous. The doctor knows what the baby is, the ultrasound tech knows, Raj knows, his Grey's Anatomy online fan group probably knows.

Sheldon: How dare you.
Amy: Oh, you heard me. Your experimental bona fides are laughable.
Sheldon: Whoa, whoa! Now you're making fun of my bona fides?
Amy: Can't make fun of something that's a null set.
Penny: I feel like I should say "damn!"
Leonard: Do it.
Penny: Damn!

Amy: Sheldon, I've made more than enough accommodations for you. We're both grown adults. We've been far more intimate than this. If you don't want to snuggle, fine. But we're not building a pillow wall.
Sheldon: Okay, well, I am sorry. I'm just worried that my sensitivity to temperature could make this a rough night. And no offense, but your bottom radiates enough heat, I'm surprised there aren't iguanas lying on it.

Penny: So, what do you want to do?
Leonard: I know exactly what we are gonna do.
Penny: Really? You're a genius, and that's the first thing you come up with?
Leonard: Hey, Sheldon's not here, so we are going to put on music and dance in our underwear.
Penny: Ugh. Can we just have sex?
Leonard: Oh, don't worry. Once you see my sweet moves, sex is inevitable.

Leonard: Keep M&Ms in your pocket in case you have to wait in a long line.
