Stuart: Well, uh, let's see. You've got your basic clean-cut good guys, Superman, Spider-Man, Captain America. Then you have your darker anti-heroes, your Batman, your Wolverine, Punisher.
Amy: Ooh, I do love a bad boy.
Penny: As evidenced by your boyfriend and his fear of hamsters.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

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?

Howard: I'm not signing a prenup.
Penny: All right, Howard Wolowitz, listen up! You sign anything she puts in front of you, because you are the luckiest man alive. If you let her go, there is no way you can find anyone else. Speaking on behalf of all women, it is not going to happen, we had a meeting.

Raj: Are they actually arguing about comic books?
Leonard: No, that can't be right.
Howard: Maybe "Thor's Hammer" is a new color of nail polish.

Bernadette: Why are they staring?
Amy: Who cares? Just soak it in. Hello, boys.
Stuart: Oh, hey. (To the other customers) Could you please stop staring? They're just girls. It's nothing you haven't seen in movies or in drawings.
Penny: Hey, Stuart.
Stuart: What brings you guys here?
Bernadette: We were looking for a recommendation about comic books.
Stuart: Oh, well, I recommend you don't open a store and sell them.
Penny: No, we were just wondering why the guys like this stuff so much, so we thought wed give it a try.
Stuart: Oh, okay. What do you think you might be into? Superhero, fantasy, graphic novels, manga? (To the customers) I swear I will turn a hose on you.

Raj: Insurance will replace your car, it won't defunk my junk.
