Leonard: With all the TV Sheldon was talking about, I had the greatest idea ever. It even blows away my idea for a Star Wars themed coffee shop called Brewbacca's. You need to watch Buffy the Vampire Slayer. It is the perfect show for the two of us. It's got action and jokes and hot vampires and romance. I cannot oversell this. What do you say?
Penny: It's six thirty in the morning.
Leonard: I thought you grew up on a farm.

Amy: I'm sorry you're upset. You know, Sheldon, sometimes people seek the comfort of physical contact in moments like this.
Sheldon: I am not flying back to Texas just so my mom can give me a hug.

Sheldon: No, that's the season two finale. That was quite the cliffhanger. I'm going to re-watch it before season three starts.
Leonard: There is no season three. They canceled that show.
Sheldon: Well, they can't cancel it. It ended on a cliffhanger.
Leonard: They did.
Penny: Uh, Sheldon, there are two dumplings left. Do you want them?
Sheldon: Dumplings? Don't you understand what's going on here?
Penny: As a rule, no.

Howard: Keep reading. What does it say?
Raj: No, no, I don't know if I should. If she wanted me to know about her blog, she would've told me. It's almost like I'm reading her diary.
Howard: It's exactly what it's like. Keep reading.
Raj: No, this is creepy.
Howard: Oh, I think we were looking at creepy in the rear-view mirror when I put up that camera.

Sheldon: That show ended with all the residents of New York either dead or unconscious. Oh, now I'll never know what happened.
Penny: Well, why don't you make up your own ending?
Sheldon: Oh, sure, what a wonderful idea. And after that, I'll make up my own rules of oral hygiene. You know, instead of flossing, I'll rub pudding on my gums.

Sheldon: Oh, dear. Penny, have you been recording shows on our DVR again?
Penny: No.
Sheldon: Answer honestly. This is not a trial. That'll come later.

Leonard: Come here. Tell you a secret?
Penny: What's that?
Leonard: With all these women chasing me, I kind of do feel like Captain Kirk.
Penny: Can I tell you a secret?
Leonard: Sure.
Penny: Keep talking about Captain Kirk, and we're all gonna stop.
Leonard: (impersonating William Shatner) Message received.

Howard: Relax. Everything's gonna be fine. Before I met Bernadette I was in here every other day. Uh, little tip, turn off your I Like Big Butts ring tone before you go in.

Howard: Do you really think you should be drinking right now?
Raj: How else am I supposed to talk to the Human Resources lady?
Howard: I don't know. Seek professional help?
Raj: I did. The guy at the liquor store said this stuff tastes great in coffee.

Sheldon: It has been pointed out to me that some of the things I said to you could be construed as offensive, and I would like to offer you my sincerest apology.
Alex: Thank you, Dr. Cooper.
Sheldon: Yeah, additionally, you should know that the university has mandated that I take an online sexual harassment seminar so this sort of thing doesn't happen in the future.
Alex: Okay.
Sheldon: Yeah. Now, unfortunately, uh, my time is much too valuable to waste on nonsense like this, so, um, I'm gonna need you to take it for me. Oh, and, uh, you'd better ace it, they're pretty mad.

Leonard: Okay, come with me.
Penny: Where are we going?
Leonard: To my bedroom, so I can take everything off but those glasses. And maybe the boots.

Penny: I don't care about Alex. Fine, I care. Okay, I hate that bitch. But what really hurt is that you liked it so much. I mean, do I need to be worried?
Leonard: Of course not. No. Why?
Penny: Because, she is pretty and smart, and when you talk about work, she doesn't have to go home and look up words in the dictionary to understand what you said.

Leonard: Hang on. Are you feeling insecure? Because that's my thing, and if you take it away, I don't know what I'm bringing to this relationship.

Sheldon: Well, you, Im just saying, you know, at a certain point in a woman's menstrual cycle...
Ms. Davis: Woah! You can't talk about that, either, Dr. Cooper. Your language is entirely inappropriate, and Im gonna advise that you shut your mouth right now.

Sheldon: I don't see why I'm the one being persecuted here. Dr. Hofstadter, he was bragging about his sexual desirability to anyone who would listen. You know, and Howard Wolowitz, he spent two years using university resources building a six-breasted sex robot. Oh, and at the office Christmas party, I heard Rajesh Koothrappali refer to you several times as Brown Sugar.
Ms. Davis: Hofstadter. Wolowitz. And the last one was Rajesh Koothrappali?
Sheldon: Yes. No, yeah, but in his defense, that wasn't racist. He's also brown.
