Stuart: Listen to this. I-I was ringing up a customer, and I heard someone say, "Hey, there's a line," and I looked, and there was.

Stuart: Oh, look at that. Neil Gaiman tweeted about my store!
Howard: What did he say? Uh, "Next time you're in Pasadena, check out The Comic Center. Great vibe, old school, the owner really knows his stuff." Isn't that amazing?
Sheldon: Well, uh, it's no Sandman, but I guess we can't expect everything he writes to be a masterpiece.

Sheldon: Can you see Mercury? Can you see it?
Raj: One second.
Amy: You know, the Greek version of Mercury, Hermes, was worshipped in Athens by the carving of giant wooden phalluses.
Sheldon: Please, Amy, get your mind out of the ancient Athenian gutter.

Sheldon: What am I supposed to do now if I want to hang out and read a comic book?
Stuart: Go sit on the couch.
Sheldon: Next to a stranger? If I'm going to sit, read, and ignore a woman, it's going to be my fiancée.

Raj: This baby's got a ten-inch diameter with f/10 ACF optics.
Howard: And tonight Mercury is at its highest elongation.
Sheldon: It makes far-away things seem close, and Mercury is a planet.
Penny: I know Mercury is a planet. But the-the other thing was helpful.

Stuart: Obviously, vibranium is the most powerful metal in comics.
Raj: What, more powerful than adamantium?
Sheldon: He's right. Wolverine's claws, Ultron's outer shell. Need I go on?
Howard: You don't need to, but you probably will.

Sheldon: You know what? Just give me a copy of Action Comics 1000, and I'll be on my way.
Stuart: Sorry. All out.
Sheldon: Now you just let people come in and buy them? I didn't realize your soul was also for sale.
Stuart: Well, it wasn't, but, uh, make me an offer.

Stuart: I am really sorry. I will make it up to you. But it won't be with a Val Kilmer Batman figurine (laughing) because some sucker's buying that right now. [to the customer] (laughs) Not you. This is great.

Penny: Look, I'm serious. The other day at work, I had this great idea, but no one was listening to me. And then five minutes later, Paul said the same thing, and they practically carried him around the room.
Leonard: Oh, well, what was it?
Penny: Well, CPK for lunch, but that's just one example.

Sheldon: No I'm not annoyed that she's a woman. I'm annoyed, and she's a woman.
Amy: No, I get that. I'm annoyed and I'm a woman.

Sheldon: It's just, Stuart knows my likes and dislikes. And I can count on his discretion if I pick up the occasional back issue of Superman's Pal Jimmy Olsen. Which I don't.
Amy: Well, don't think of her as a stranger. Just think of her as a a friend you haven't berated, lectured or condescended to yet.
Sheldon: I hadn't thought of it that way. Thank you.
Amy: You're welcome.

Sheldon: Just look at her over there. She just started, and she gets to put up "Staff Picks." I've been coming here for ten years, I still can't put up "Sheldon Dislikes."

Sheldon: Excuse me. I was wondering if you could recommend something.
Denise: Oh, sure. You want to tell me what you like?
Sheldon: I would not.
Denise: All right, well, you're wearing a Green Lantern shirt, so I'm guessing you're a DC fan. Although that's from the Alan Scott era, so you're probably not super into the current run. How would you feel about an alternate history where World War I was fought with dragons and magic?
Sheldon: That's what I wanted the theme of my tenth birthday party to be!

Neil Gaiman: You know, if you're interested in alternate histories, Neil Gaiman wrote one called 1602.
Sheldon: I'm sorry, we're in the middle of something here.
Neil Gaiman: It is pretty good, actually. He takes the Marvel superheroes and he puts them into Elizabethan England.
Sheldon: Let me guess, everyone thinks the X-Men are witches.
Neil Gaiman: Yeah.

Penny: No, there's something fuzzy.
Howard: Is it your teen years?
Penny: No. Yes. Shut up.
