Howard: I can't believe you pulled this all together overnight.
Raj: Uh, if I had more time, I could have gotten the Blue Man Group. One of them goes to my dry cleaner. Who, by the way, hates him.

Howard: You really saved the day.
Raj: Well, it's not for you. It's for Halley.
Howard: And I'm sure she'd appreciate it, if she knew what's going on or who you are.

Sheldon: Morning. Happy birthday.
Amy: Yeah, sure.
Sheldon: Did you sleep at all?
Amy: No. You?
Sheldon: I passed out on the toilet once. I don't know if that counts.

Sheldon: And besides, it's our birthday tradition.
Amy: You think you can do it while I lie perfectly still and you don't touch me?
Sheldon: I can try. (doesn't move, exhales) Want to do it again?

Leonard: No, no, I-I'm serious. If there's things we want to do, let's start doing them.
Penny: Okay. Well, we've never been on a big trip together.
Leonard: I would love that.
Penny: Okay, there's something for your letter: "Considered going on a trip."

Raj: Those are the only other people you invited? What about the kids from the Daddy and Me class?
Howard: Oh, grow up.

Sheldon: Although I-
Raj: It's me, Sheldon. He-He's calling me a baby.
Sheldon: No, I don't know. I saw Leonard put his keys in his mouth today.

Howard: Hey, guys, there's a change of plans. We are having a party for Halley's birthday after all. Turns out Bernadette and "anyone who's not a heartless monster" thinks that's the right thing to do.

Raj: Are you kidding me? You're not gonna invite me to Halley's birthday? I'm her godfather; that means something.
Howard: Or - hear me out on this - it doesn't.

Raj: So-so-so you're just apologizing because you need something?
Howard: Yes, and I think it's pretty mature of me to admit it.
Raj: Well, that's very insulting.
Howard: Right again.
