Sheldon: Penny, if you wouldn't mind, I'd like to have a conversation about girls.
Penny: I had a weird feeling we'd have a talk like this sooner or later. Are you finally fuzz in weird places?
Sheldon: Penny, please. I'm on the horns of a relationship dilemma. And for the record, I had a full pubis of hair by the time I was 19.
Penny: And for the record, bleugh.

Penny: I have no reason to ... "B" mad at you. Minus.
Leonard: Wow.
Penny: That's right. On my paper. Not yours, mine, you punk-ass elf.

Bernadette: Why would you be embarrassed to tell us?
Penny: No, I'm not embarrassed. I just didn't want anyone to know because I haven't told Leonard yet.
Amy: Why wouldn't you tell Leonard?
Penny: Because it's me going back to school, and he's gonna be all "You can do it!" and "How can I help?" and "I'm so proud of you". Ugh!

Penny: Spaghetti okay?
Leonard: It's crunchy. Just the way I like it.
Penny: Yeah, I don't think the water was really boiling.

Leonard: Am I allowed to ask how the class is going?
Penny: It's really good. We've been talking about the origins of slavery. Turn in my first paper tomorrow.
Leonard: Great topic. I can help with that. There are lots of different perspectives you can take, economic, sociological, political.
Penny: Hey hey hey, this is my paper. And my perspective is that slavery is bad. Oh, and my professor's black, so I'm pretty sure thats the right answer.

Leonard: Good morning, sunshine.
Penny: Leonard. It's eight a.m. It's like the middle of the night.

Penny: Hey, what's this?
Leonard: Uh, before you open that, um, are you familiar with the story of "The Shoemaker and the Elves"?
Penny: Elves? Come on, Leonard. It's too early for Lord of the Rings.

Amy: How'd it go with Leonard?
Penny: I don't think he'll be making that mistake again.
Bernadette: Good.
Penny: So, I know this goes without saying, but if either of you tell Leonard you helped me rewrite this paper, I will beat you both with a bag of oranges.

Penny: Now, ladies, we got a B-minus on this paper. I think if we put our heads together, on the next one we could get an A.
Bernadette: Uh, but we got you a B-minus on purpose to make it believable.
Penny: Believable? You saying I'm not smart?
Bernadette: No, no!
Amy: You're smart.
Penny: That's better.

Bernadette: Leonard does things he doesn't like to make you happy.
Penny: Well, yeah he's my boyfriend, isn't that like his job?
Amy: Then what's your job?
Penny: Letting him make me happy.

Amy: Ladies night at the Cheesecake Factory. Does it get any better than this?
Penny: I hope so.
Amy: Question. Do you think your husband's fondness for turtlenecks is an expression of longing for his missing foreskin?
Penny: It's not getting any better.

Penny: Ugh, it's Leonard. He wants to go costume shopping later.
Bernadette: I thought you liked Halloween.
Penny: I do, it's just he wants to go to that party at the comic book store. A lot of the guys that hang out there are kind of creepy.
Bernadette: Like my husband?
Amy: And my boyfriend?
Penny: I'm-I'm sorry. Amy, you were saying something about Howard's foreskin?

Penny: I guess I could probably try a little harder.
Bernadette: You could start by taking an interest in his work.
Penny: Yeah, that's kind of a problem.
Amy: Why?
Penny: Not really clear on what he does.
Bernadette: He's an experimental physicist.
Penny: Yeah, I'm not really clear on what that means.
Amy: He takes hypotheses and designs protocols to determine their accuracy.
Penny: Yeah, you're really just making it worse.

Leonard: Oh, no, no, no, don't look in there.
Penny: What, is it secret?
Leonard: No, it's a nitrogen laser. It'll cook your eyeball like a soft-boiled egg.
Penny: Oh. You might want to put a sign on it.
Leonard: Sign right there.
Penny: Ah. Danger. Sure, sure.

Penny: What's-what's that?
Leonard: Uh, that is an integrated ion trap and time-of-flight mass spectrometer.
Penny: Wow. High-techie-techie. What's this little box?
Leonard: That is a pencil sharpener.
Penny: Ooh, low-techie-techie.
