Zack: Look up in the sky. It's a bird. It's a plane. I forget the rest.
Penny: All right. Let's get this thing over with.
Sheldon: I'm sorry. But in what universe is Wonder Woman blonde?
Howard: Relax. No one's going to be looking at her hair. Ow! I mean, ow.
Zack: Hold on. The costume came with a black wig. Where is it, babe?
Penny: No. I'm not wearing it. It looks stupid.
Zack: Come on. We're trying to win a contest here.
Penny: Forget it. I'm not wearing the wig.
Zack: Penny, there's no I in Justice League.
Howard: Well, actually.
Sheldon: Don't. He's making our case.
Zack: Okay, babe. You're kind of embarrassing me in front of my friends.
Penny: Okay. You know what? I changed my mind. I'm not going.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

Raj: I've said this before and I'll say it again: Aquaman sucks!

Zack: Whoa, you dated Penny?
Leonard: She didn't tell you?
Zack: She told me she dated a guy named Leonard. Who would have thought it was you?
Leonard: Who else would it be?
Zack: I don't know. Somebody bigger and- Yeah, sure. Why not you?

Zack: You know, I saw this great thing on the Discovery Channel. Turns out if you kill a starfish it'll just come back to life.
Sheldon: Was the starfish wearing boxer shorts? Because you might have been watching Nickelodeon.
