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.

Sheldon: I'm not Sheldon. I'm the Flash. And now I'm going to the Grand Canyon to scream in frustration. *takes two quick steps* I'm back.

Zack: You're inferring I'm stupid.
Sheldon: That's not correct. We implied you're stupid, you then inferred it.

Zack: Wow, this place is awesome. Where do they keep the Archies?
Sheldon: In the bedrooms of ten-year-old girls, where they belong.
Zack: Oh, no, you're thinking old-school Archie. It's much more sophisticated now. Like, there's two universes, and Archie's married to Betty in one and Veronica in the other. Midge is even breaking up with Moose.
Raj: No.
Zack: About time, right?
Stuart: Hey.
Zack: Hey.
Stuart: You guys finally chip in for a bodyguard?
Leonard: Uh, no. Oh, this is Zack. He's a friend of ours. Zack, this is Stuart. He owns the store.
Zack: Wow, lucky you.
Stuart: Yeah, I work 70 hours a week and average a dollar sixty five an hour.
Zack: Sweet.
Stuart: Is that sarcasm?
Howard: Uh, no, it's an indictment of the American education system.
Raj: The Archies are over here.
Zack: Yippee.

Wolowitz: You got her to have sex with you. Obviously your super power is brainwashing.

Sheldon: (Knocking at Penny's door) Penny! Penny! Penny! Penny! Penny! Penny! Penny! Penny! Penny! Penny! Penny! Penny!
Penny: What the hell is wrong with you?
Sheldon: I'm the Flash, I just knocked 30 thousand times.

Sheldon: I understand why you're upset. You're afraid that costume makes you look fat.

Sheldon: Don't worry. Wonder Woman was an Amazon. And Amazons tend to be very beefy gals.

Koothrappali: Oh, great. No Superman, no Wonder Woman? All we've got is a skinny Flash, an Indian Aquaman, a near-sighted Green Lantern, and a teeny, tiny Dark Knight.
Sheldon: Obviously, we're no longer a Justice League. We have no choice but to switch to our Muppet Baby costumes.
Koothrappali: Ooh, I call Kermit.
Sheldon: I'm Kermit. You're Scooter.
Koothrappali: Oh, man. Scooter sucks. He's the Aquaman of the Muppet Babies.

Sheldon: I'm sorry, but in what universe is Wonder Woman blonde?

Zack: Hold on. The costume came with a black wig.
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: Honey, there is no "I" in "Justice League."

Sheldon: Obviously, we're no longer a Justice League. We have no choice but to switch to our Muppet Baby costumes.
Raj: Ooh, I call Kermit.
Sheldon: I'm Kermit. You're Scooter.
Raj: Oh, man. Scooter sucks. He's the Aquaman of the Muppet Babies.

Sheldon: Good Lord how you frustrate me Leonard Hofstadter!
