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.

Sheldon: I think you should turn on the GPS.
Leonard: It is on.
Sheldon: But the turn-by-turn voice option isn't on. I know I'd feel more safe if you turn on the turn-by-turn voice option. I love the turn-by-turn voice option.
Howard: Has it really only been ten miles?

Leonard: Hey, will you steam my uniform next?
Sheldon: Interesting. Do you recall this conversation? Leonard, want to go halfsies on a steamer? No, Sheldon, we don't need a steamer. Looks like that rumpled chicken's come home to roost.

Sheldon: That's a wise policy. I once borrowed my sister's makeup for a costume contest. Got a terrible case of pinkeye. But luckily, I was going as a zombie. I won second place.

Bernadette: It's cute how excited they are. You should have seen Howard sewing his costume all week for the convention.
Amy: When did Howard learn to sew?
Bernadette: When he was a little boy, every couple months, he would have to let his mom's pants out.

(The girls enter Stuart's comic book store)
Bernadette: Why are they staring?
Amy: Who cares? Just soak it in. Hello, boys.

Penny: Look, it's fine. We're not getting married, okay? We're keeping things, you know, homeostasis.
Amy: It's so cute when she tries.

Raj: Focused Locust.
Stuart: Temple of Yip.
Sheldon: I'm sorry. Wolowitz would never play that card.
Stuart: All right, Lesser Demon Turtle.
Sheldon: Fairy God Monster, I win. Your desperate need for friendship makes you weak.

Bernadette: Why don't you stand up to them?
Howard: What am I supposed to say?
Bernadette: I don't know. Say, being mean is lame, what's cool is being nice.

Howard: Great, I'll do that when I want to be the first guy in space to get a wedgie.
Bernadette: Do you want me to call somebody at NASA?
Howard: No. My mom already tried that. It only made things worse.

Raj: So, what are you guys doing later? Stuart and I were thinking of going out for a drink.
Stuart: We're gonna try to meet some girls.
Raj: 'cause that's what we do.
Stuart: Watch out, ladies, a little coffee and cream coming your way.
Raj: In case you didn't follow that, I'm the coffee.

Sheldon: Do you remember how upset I was when they replaced Edward Norton as the Hulk?
Leonard: Yes, you walked around for a week saying, Sheldon unhappy with casting choice.
Sheldon: But, then Mark Ruffalo was the Hulk in The Avengers, and he was even better.
Leonard: What's your point?
Sheldon: Call me a romantic. I like to think that your Mark Ruffalo is still out there somewhere.

Sheldon: My point is, I don't like when things change. So, regardless of your feelings, I would like you to continue dating Leonard. And also, while we're on the subject, you recently changed your shampoo. I'm not comfortable with the new scent. Please stop this madness and go back to green apple.

Sheldon: Oh, I was having a little trouble sleeping and I just thought, uh, seeing as you're up, we could talk.
Penny: Talk about what?
Sheldon: Oh, I don't know. Uh, weather. Uh, fish you could do carpentry with. Why Leonard is such an attractive and desirable boyfriend. Yeah, pick one. Your choice.
Penny: Sheldon.
Sheldon: Did you know that Leonard has a perfect driving record and enjoys the insurance discounts that go along with that? Hubba-hubba.
Penny: Okay, go home, crazy man.
Sheldon: Yeah. Did you know that while Leonard is not considered a tall fellow in our country, in today's North Korea, he's downright average. Hey, talk about a keeper.

Sheldon: *Knock, knock, knock* Leonard? *Knock, knock, knock* Leonard? *Knock, knock, knock* Leonard?
Leonard: What?
Sheldon: Are you sleeping?
Leonard: I was. Now I'm having a nightmare.
