Penny: I don't know what to say.
Leonard: Don't say anything. ... I mean you could say thank you, I did just buy you a car.

Penny: It's just so humiliating.
Leonard: "So humiliating?" Am I driving you to the Cheesecake factory or - I'm sorry, I'll stop. I'll stop.

Sheldon: Oh apple juice stay where you are.

Penny: Come on, let's just get this over with.
Leonard: "Let's just get this over with?" Am I driving you to the Cheesecake Factory or are we having sex?

Raj: I give you one simple thing to do: contact a complete stranger and make her fall in love with me, and you blow it!

Bernadette: I said to stop insulting each other. I didn't tell you to take him on a romantic getaway.

Howard: How do I know what you said? Damn you and your noise-cancelling breasts.

Howard: What now?
Sheldon: I have to go to the bathroom.
Howard: You just went to the bathroom.
Sheldon: But I didn't use it because it didn't seem safe. Despite all my emails, the toilet didn't have a seatbelt.
Howard: Well, it still doesn't.
Sheldon: I realize that but safety concerns went out the window two apple juices ago.

Howard: I'm an astronaut and you know it. You just don't like admitting it because you're jealous.
Sheldon: Well, truth be told, as a child I did dream of going to space. Those astronauts were my heroes. And when you got to go, it was hard for me.
Howard: Thank you.
Sheldon: Because it made me realize they'll just send anyone up there.

Bernadette: You excited for Texas?
Sheldon: Oh, very much so.
Howard: It's not everyday you get to tour NASA with a real astronaut.
Sheldon: Ohh, who's the real astronaut?
Howard: ... Buzz Aldrin.
Sheldon: Oh, yay!

Sheldon: My spot on the couch has a great view of a window. Sometimes I can see space battles through it. It's called a TV.

Howard: Hey. Good news, somebody in this room gets to take a ride on a rocket.
Bernadette: Fine. Can I at least shower first?
Howard: No, not that. Although you already agreed to it, so no takebacks.

Leonard: You make a lot of sense. I like this table and I'm getting it.
Penny: Really, this one?
Leonard: That one.
*Penny nods*
Leonard: Damn right I like that one.

Penny: You're a grown man. You should be able to pick whichever Hobbit you want. ... I wish you wouldn't, but one problem at a time.

Penny: Ooh, this one looks nice.
Leonard: No, Sheldon doesn't like reclaimed wood.
Penny: Why not?
Leonard: He's afraid the original owners will come back.
