Sheldon: Penny, you're an expert on trading sexual favors for material gain, walk him through this.

Raj: Here's what I wonder about zombies. What happens if they can't get any human flesh to eat? They can't starve to death, they're already dead.
Howard: You take this one. I spent an hour last night on how do vampires shave when they can't see themselves in the mirror?
Sheldon: Well-groomed vampires meet in pairs and shave each other. Case closed.

President Siebert: So, listen, fellas, who's up for a little party this Saturday night? Open bar, good eats, might even be a few pretty girls.
Raj: Sounds great!
Howard: I'm in!
Sheldon: Hold on. Just because the nice man is offering you candy, doesn't mean you should jump into his windowless van. What's the occasion?
President Siebert: Just a little fund-raiser for the university.
Sheldon: Aha! The tear-stained air mattress in the back of the van.

Leonard: Are you sure this is right?
Penny: Yeah, just tuck that part in your pants; you'll be fine.
Howard: Okay, let's go smooch some rich, wrinkled tuckus.

President Siebert: Mrs. Latham, I'd like you to meet three of our outstanding young researchers. This is Dr. Leonard Hofstadter, Dr. Rajesh Koothrappali and Howard Wolowitz.
Mrs. Latham: Well, what happened to you, Wolowitz, couldn't stick with it long enough to get your PhD?
Howard: I'm an engineer. Most engineers don't bother with a PhD. But you may be interested to know I designed the zero-gravity waste-disposal system for NASA.
Mrs. Latham: Got it. You're a space plumber.

Sheldon: And so, instead of bowing to pressure, and going to that pointless soire, I stayed right here and did a load of whites.
Amy: (On webcam) Well, normally I respect your macho rebellious attitude toward The Man, but, in this case, I think you'vee made a foolish mistake.

Leonard: On the bright side, I don't think President Siebert will be making us go to any more fund-raisers.
Howard: It was so much easier at my bar mitzvah. The old people just came up to you, pinched your cheek and handed you a savings bond.
Raj: Oh, don't be such gloomy gusses. Look at the size of these shrimp! At what point do we start calling them lobsters?

Leonard: Face it, Raj, we crashed and burned tonight.
Mrs. Latham: Oh, you didn't do that badly.
Leonard: Mrs. Latham, the first machine I turn on in the morning is the helium-neon laser, 'cause it needs to warm up.
Mrs. Latham:: I no longer care, dear.

Mrs. Latham: I no longer care, dear. But don't worry, I really enjoyed meeting you this evening.
Leonard: You're kidding. That was good for you? 'cause I was sweating through my T-shirt.
Mrs. Latham: Excellent! There's nothing I like better than making smart people feel ill at ease.
Leonard: Why?
Mrs. Latham: Oh, I don't know, it's one of the fun things you get to do when you have lots of money. Watch. (To Raj) Hey! Who said you could eat that shrimp? See? Fun.

Sheldon: No, no, no, I'm just here for your money. I don't want to shake anyone's germy hands. Explain it to them, Siebert.

Sheldon: Cooper-Hofstadter residence. Go for Cooper. Good morning, Mrs. Latham. Well, yes, of course I remember you. A woman well past her prime seeking to augment her social status by doling out her late husband's ill-gotten gains.
So, how much money are you going to give me? I'm not crazy, my mother had me tested. Well, if you're not going to give me money, then why are you calling? She wants to talk to you. Who's crazy now?

Sheldon: Okay, I see what's happening.
Leonard: What?
Sheldon: My stature intimidates her, so she's using you to get to me. Crafty old gal.
Leonard: Excuse me, but you are not the only distinguished scientist in this apartment. I've been published in peer-reviewed journals, I received a Dissertation of the Year award for experimental particle physics.
Sheldon: No, that can't be it.

Howard: Hey. How was dinner?
Leonard: Swell. I need a drink. Do we have any alcohol?
Sheldon: No. But we have potatoes, I could make you vodka. It'll take two weeks.

Leonard: Well, Mrs. Latham said she was seriously considering donating money so we could get a cryogenic centrifugal pump.
Sheldon: Oh, wow!
Howard: Yes!
Leonard: Then she stuck her tongue down my throat.
Sheldon: Why?
Penny: Okay, we can't keep explaining everything. Read that book we got you.

Howard: Are you telling us that old lady wanted to have sex with you in exchange for giving your department millions of dollars?
Leonard: I think so.
Howard: You lucky duck.
Penny: You're really a broken toy, aren't you?
