Professor Proton: Is, uh, is he dangerous?
Leonard: Actually he's a genius.
Sheldon: I am.
Professor Proton: That doesn't answer my question.

Raj: Uncle Howard, Cinnamon's here for her sleepover party.
Howard: You know if you had a stroke, she'd eat you, right?
Raj: And it would be my pleasure to be her num-num.

Sheldon: Professor Proton hosted my favorite science show when I was a child. I never missed an episode. He demonstrated scientific principles using everyday objects.
Leonard: It was pretty cool.
Penny: Aw, it's so cute when you use the word cool wrong. Like when kids say pasgetti.

Raj: Hey, I just found out that I have to be at the telescope lab all weekend. Any chance you and Bernadette could take care of my dog?
Howard: Why don't you put her in a kennel?
Raj: Why don't you put your mother in a home?
Howard: To be honest, she'd do better in the kennel.

Ms. Davis: Well, according to Ms. Jensen, you said that she was a slave to her biological urges and called her an egg salad sandwich. I don't even know what that means, but I'm gonna go ahead and tell you you can't say it.
Sheldon: Oh, I see the confusion here. No, no. Alex thought I was singling her out. No, I meant that all woman are slaves to their biological urges, you know? Even you. You're a slave.

Raj: Howard built a sex robot.
Howard: That is not true. All I did was build a robot.
Ms. Davis: Did it have six breasts?
Howard: I'm sorry, I'm a feminist, I don't notice things like how many breasts a robot has.

Sheldon: But I came to file a complaint. Somebody has made me feel uncomfortable in the workplace by using language of an inappropriate and sexual nature.
Ms. Davis: And who was that?
Sheldon: You, you dirty birdie. I thought about the things you said to me yesterday, and I realized I'm deeply offended. Now, be a dear and get me one of those complaint forms.

Sheldon: And thanks to you, I know better than to ask if you're menstruating. And based on your behavior, I don't have to.

Sheldon: Anyway, despite the fact he has a girlfriend, Shilly-Shally has been the recipient of inappropriate workplace flirtations from a young lady.
Amy: It's your assistant Alex, isn't it?
Sheldon: No, no, no. This is Tondelaya della Ventimiglia.

Sheldon: Okay, look. It's not really about Ricardo and Tondelaya. It is really about her boss, who doesn't quite know how to handle this situation and could use your advice. Which is surprising because Dr. Einstein von Brainstorm, he's usually pretty smart about these things.

Sheldon: Well, you remember when you told me I talk in my sleep? Well, it occurred to me that, like most things I say, it's probably pure gold. So I started recording it all, and now Alex gets to comb through eight hours of what I like to call Sheldon After Dark.

Raj: I did the research. Tony the Tiger, Dig'em the Frog, Cap'n Crunch, Toucan Sam, Count Chocula, Trix the Rabbit, Snap, Crackle and Pop. Not one cereal mascot is a girl. It's a total breakfast sausage fest.
Leonard: Are we done with this?
Raj: Almost. Franken Berry, Boo Berry, Sugar Bear and the Honey Nut Cheerio bee, I believe his name is Buzz.

Raj: Your assistant is totally hitting on this jerk and he loves it.
Sheldon: Well, that's not acceptable. I mean, I'm her boss. She needs to be solely focused on my needs, not distracted by your pasty, androgynous brand of sexuality.
Leonard: I'm androgynous?
Sheldon: Oh, please. look at you with your pouty bee-stung lips.

Sheldon: I want to thank you all for coming on such short notice. In the past, I've reached out to each of you individually, but I believe my present situation requires the collective wisdom of the group. Which, as you can see from your commemorative t-shirts, I have dubbed Sheldon Cooper's Council of Ladies.

Bernadette: Who's involved?
Sheldon: Well, a short bespectacled colleague of mine who lives in the shadow of his brilliant roommate. Let's call this colleague Ricardo Shilly-Shally.
Penny: You're talking about Leonard.
Sheldon: No, no, Shilly-Shally has red hair and he briefly served in the Mexican Navy.
