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.

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

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.

Penny: The new neighbors are weird.

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

Leonard: He startles easily, so, please, no flash photography.

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

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.

Sheldon: No, I know, but plenty of things are addictive after a single exposure. I mean, crack cocaine, nicotine, Pringles. You know, once one pops one just can't stop.

Raj: Well, I think the first thing we should get rid of is that tone.

Bernadette: Sorry I flipped out on you. I think it's just hormones.
Raj: I think you were mean before you were pregnant, but it's fine.

Penny: Now Sheldon's popular? What is happening?!

Sheldon: I am cool. This is YooHoo. Chocolate milk's delicious, watery cousin.
