Sheldon: Perhaps I should explain. While working with Koothrappali, we discovered an asteroid, and I named it after you.
Amy: Oh, Sheldon, thank you. That's so romantic. But what about Rajesh? He was okay with you choosing the name?
Sheldon: Well, it took a little negotiating, but I wore him down. Uh, we get the asteroid, and if you and I have children, they all have to be named Rajesh.
Amy: All of them?
Sheldon: Even the girls.
Amy: Okay, I think I know what to say now.

Amy: Okay, what is going on?
Penny: We just want you to be prepared for any surprises that could happen tomorrow.
Amy: What surprises?
Bernadette: We don't want to spoil anything, but you should know that Sheldon said he's ready to be physical.
Amy: You shut your damn mouth! You actually heard him say this?
Penny: Yes, he said he wants to do something to show you how much you mean to him.
Amy: I can't believe it. I don't know what to say.
Bernadette: Well, we're really happy for you and we know how much-
Amy: I do know what to say. Let's get me waxed!

Sheldon: Sheldon Cooper does not get lucky.
Amy: You and me both, brother.

Amy: I guess it must have been back when I was in the Girl Sprouts.
Bernadette: Girl Sprouts?
Amy: My mom made it up as an alternative to the Girl Scouts. She didn't want me selling cookies on some street corner like a whore.

Howard: You know, once we get the house back to ourselves, we can be romantic in any room we want.
Bernadette: Great. I can finally show you where the laundry room is.

Raj: Come on, a medium-sized asteroid is still an interesting discovery.
Sheldon: I suppose it could end up on a collision course with Earth and destroy life as we know it.
Raj: You dream different than me.

Leonard: You know what'd be nice? Name it after your girlfriends. Show them how much you care.
Raj: That is a great idea.
Sheldon: It's perfect. It appears romantic, but it's really just a rock in space that gets me out of Valentine's Day forever.
Raj: So, uh, what were you thinking? Combine their names?
Sheldon: I like it. Yeah, we'll take the "Am" from Amy and, uh, the "Y" from Emily.
Raj: That's just Amy.
Sheldon: Exactly. See how well we work together?
