Leonard: Stuart, have you thought about what you'd do if Howard sells the house?
Stuart: And there goes the mood.

Howard: Hey guys. I just want everyone to know tonight's not a sad occasion.
Bernadette: Yeah, we just want to have the kind of dinner that we've all had here so many times before.
Howard: Good food. Good friends. And, sometime around midnight, heartburn that makes you pray for death.

Penny: This food is amazing.
Raj: And not a vegetable in sight.
Howard: That's not true. We've got tomatoes right here.

Amy: All these bright people sitting around a table by candlelight. It feels like we could be an eighteenth century French salon.

Sheldon: Indeed. Penny, a salon is a gathering where intellectuals entertained each other with sparkling conversations about the issues of the day.
Penny: Huh. So it's like The View.

Sheldon: Hi. Hello. And a special hello to Leonard, who needs to be mentioned by name.
Leonard: Subtle.
Sheldon: But you got it right.

Amy: You applied for a mission to be a colonist on another planet and couldn't be bothered to tell me?
Sheldon: Would you have approved?
Amy: Of course not.
Sheldon: Well, based on your reaction, it looks like I made the right choice. Isn't that right, Giuseppe.

Leonard: I got you something for Valentine's Day and I was too embarrassed to give it to you.
Penny: Why?
Leonard: Because I got it at the dirty store.
Penny: You went to the dirty store without me?
Leonard: In sun glasses and a hat after I parked two blocks away.

Sheldon: Being in close quarters, cleanliness is important. My hygiene is impeccable. In fact, animals don't trust me because I smell like nothing. Literally, nothing.

Leonard: We cover ourselves in body paint and then we get on this big canvas and do our thing.
Penny: Woah, that's kind of a big step for a guy who only recently agreed to take his socks off.

Penny: No, come on, I wanna do it. Let's you, me and your very, very pale feet make some art.

Bernadette: What's happening?
Howard: Raj was snooping through Emily's drawers and broke one.
Bernadette: Oh, I'm gonna miss her.

Penny: Did we move at all?
Leonard: Maybe a long the Z axis, but X & Y are looking pretty sad.

Penny: So, what do you think?
Leonard: I thought it would be a little more ... just more.
Penny: I'm not even sure why we were out of breath.

Howard: How are the taxes going?
Bernadette: Okay, but you've got a lot of receipts for the Lego store in here.
Howard: Those are business expenses. You can write those off.
Bernadette: A $200 R2-D2 is a business expense?
Howard: Oh, Bernie, you're gonna have to sound a lot more confident when we get audited.
