Howard: Hell hound.
Raj: Who let the satanic dogs out?

Sheldon: Oh, what fresh hell is this?
Biosuit Nurse: Wait, you can't leave here, you've been exposed.
Sheldon: (Covering his face with his shirt) No, I haven't. It's all good.

Raj: Sheldon, that's my water.
Sheldon: Oh, dear Lord!
Leonard: That's not your water.
Raj: I know.

Priya: What happened?
Bernadette: Howard's mother had a heart attack because I have sex with him and she can't.

Priya: Indian parents are very protective of their children.
Howard: Right. Whereas Jewish mothers take a casual la-di-da approach to their sons.

Leonard: I'm the king of foreplay.

Sheldon: 'He drank from Leonard`s glass' - the words they will be carving into my tombstone.

Sheldon: Howard, I have to go to the bathroom and no one will take me home.
Howard: What's wrong with the bathroom here?
Sheldon: Pneumococcus, streptococcus, staphylococcus and other assorted cocusses.
Howard: Sheldon, my mother is on her deathbed and my fiance is grief-stricken over putting her there. I'm not taking you home!
Sheldon: Will you at least go with me to the restroom here so you can open the door and flush the urinal?
Howard: No!
Sheldon: This might be a good time to point out, Howard, that friendship requires a certain give and take.

Raj: Rotting Zombie. Sheldon's new Facebook picture.

Penny: Oh, my God, you’re about to jibber jabber about jibber jabber.

Wolowitz: Have you told your parents you're dating this short glass of skim milk?

Sheldon: I gargled with tequila. I may have swallowed a tiny bit.
Leonard: You all right?
Sheldon: Fine, thank you for asking. I love you so much.

Bernadette: You're a putz. Do you what that means?
Howard: Yeah. Do you?

Leonard: Does your family have a history of heart disease?
Wolowitz: My family is the history of heart disease. There's a cave painting in France of one of my ancestors doing this. *Mimics heart attack*

Sheldon: Zandor, wizard of the north. Ha! I win!
Howard: If you skip the part about under a two week quarantine because you were exposed to a deadly disease, absolutely.

Penny: Hey.
Sheldon: Hello.
Penny: Haven't seen you in a while. How's it going?
Sheldon: Oh, other than waiting out the exponential growth period of the virulent organisms trooping through my micro-villi into my circulatory system, hunky-dory. (Penny laughs) Did I say something amusing?
Penny: I don't know. Maybe, I have no idea what you said.

Doctor: Mr. Wolowitz?
Howard: Is she okay?
Doctor: It wasn't a heart attack. She's awake, she's resting comfortably. We're still running a few tests.
Howard: Can I see her?
Doctor: Actually, she said, and I quote, she'd like to see the little Catholic girl first.
Bernadette: Me? Why me?
Howard: Jews have been asking that for centuries. There's no real good answer.

Priya: My brother had a group of friends like this in India. They dressed up in leotards and goggles and called themselves the New Delhi Power Rangers.
Penny: How old were they?
Priya: Not as young as you'd want them to be.

Bernadette: Okay, well, wish me luck.
Howard: Dont worry, you'll be fine. Let's just hide Mr. Cross. If it touches her, it burns.

Penny: Okay, you know what? You are unbelievable. You buy all these superhero T-shirts, but when it's time for you to step up and do the right thing, you just hide in the laundry room.
Sheldon: Fine, I'll go. Just for the record, my Aunt Ruth died in a hospital. She went in to visit my Uncle Roger, caught something and bit the dust a week later. The two of them now share a coffee can on my mother's mantel.

Howard: Is it just me, or does she sound sexy when she's angry?

Howard: So I knocked down the bathroom door, picked up my poor unconscious mother, carried her to the car, and drove like a madman to the emergency room.
Bernadette: You're a real hero, Howard.
Howard: No, I did what any son would do.
Penny: Hang on a second, you picked up your mother? Her own legs are barely able to do that.
Howard: I was filled with adrenaline. It happens to be how women lift cars off babies.
Penny: Yeah, I'm saying, it'd be easier to lift a car.

Howard: What can I tell you? After I found the courage to put her pants back on, I was unstoppable.

Leonard: So, how is she?
Howard: They're running tests. I don't know. It may have been a heart attack or heart-attack-like event.
Penny: What's the difference?
Sheldon: A heart-attack-like event is an event that's like a heart attack.
Penny: Thanks for clearing that up.

Sheldon: Regardless, coronary problems are eminently treatable. What's more likely going to kill Howard's mother are the antibiotic-resistant super-bugs festering in every nook and cranny of this hospital.
Penny: Okay, you're not helping.
Sheldon: Disagree.

Bernadette: So it's probably genetic.
Howard: Well, maybe. Mom also had just gotten some news that might have upset her.
Bernadette: What?
Howard: It's not important.
Bernadette: Come on, Howard, I'm going to be your wife. You can share anything with me.
Howard: You'd think that. But no.
Bernadette: You told her we were going to get married and she had a heart attack?
Howard: You can't take that personally.
Penny: How else is she supposed to take it?

Howard: What you've got to keep in mind is that ever since my dad left, I've been the whole world to my mother. I mean, she'd be threatened by any woman who can give me what she can't.
Bernadette: You mean sexual intercourse?
Howard: Well, when you say it like that you make it sound creepy.

Priya: Nice of you to come for Howard.
Penny: Well, he's my friend. It's what you do. (Laughs)
Priya: I'm sorry, did I miss something?
Penny: It's just so weird. Howard Wolowitz is my friend. You know, once he tried to stick his tongue down my throat and I broke his nose.
Priya: That's a little easier to believe than he's your friend.
Penny: Yeah, tell me about it.

Leonard: That's nice that they're getting along.
Raj: Your girlfriend and your ex-girlfriend are hanging out together? Oh, yeah, that can only be good for you.
Leonard: What are you talking about?
Raj: One of them broke up with you. Do you really want her telling the other one why?
Leonard: I don't care. I don't have anything to hide.
Raj: Good, good. Then you have nothing to worry about.
Leonard: No, I do not. You are a mean little man.

Raj: You'd think it'd be because my parents didn't love me, but actually they loved me a great deal.
Howard: Bernie, it's not you. She's just set in her ways.
Bernadette: How can we be together if the thought of us getting married might kill your mother?
Howard: It's the circle of life, sweetie. One day our son will marry someone and it will kill you.

Doctor: You brought a Catholic girl home to your mother?
Howard: Yeah.
Doctor: Why don't I write you a prescription for Xanax.

Penny: You want to talk about crazy mothers, Leonard's mom wouldn't give him any sort of approval growing up.
Priya: Oh, the poor thing.
Penny: It makes him desperate to please women. That's why the foreplay goes on and on.
Priya: It does, doesn't it?
Penny: It's like he's trying to win a prize. A word of advice, don't doze off. You will never hear the end of it.

Leonard: Every once in a while, before we'd go to bed, I'd put on a little show for her.
Raj: What do you mean, a show?
Leonard: Well, you know, the way I took my clothes off.
Raj: Like, to music?
Leonard: I'd look pretty stupid if there was no music.
Raj: So you'd do a striptease?
Leonard: I wasn't swinging around a pole.
Raj: Good, good.
Leonard: There was one time I put body glitter on.
Raj: Well, I don't think you have to worry about Penny telling my sister that.
Leonard: No, she wouldn't.
Raj: Your big problem is me telling her.
Leonard: You really are a mean little man.

Bernadette: She thinks she got food poisoning from that deli and she just wanted to make sure I was okay.
Howard: And are you?
Bernadette: No, because I'm engaged to a putz! You let me believe I was the reason she had a heart attack.
Howard: Well, based on the available evid-
Bernadette: Shut up! She said I'm a wonderful girl and that you're lucky to have me.
Howard: Where are you going?
Bernadette: (sounding like Mrs. Wolowitz) To the toilet! Is that okay with you?

Priya: Hey, have you and Howard started planning your wedding yet?
Bernadette: Yeah. Were thinking of having it on a cliff overlooking the ocean.
Howard: Nothing soothes those pre-wedding jitters like the thought of falling and drowning.

Penny: Hey, do me a favor and take table seven.
Bernadette: You mean the one with my one hundred and eighteen-pound rock-hard stud of a fianc who's prone to canker sores and pinkeye?
Penny: Nah, I prefer to look at it as the one with my ex-boyfriend and his gorgeous, successful and sophisticated girlfriend, who makes me feel like a toothless Okie.

Bernadette: Do you want me to spill hot soup on her?
Penny: Oh, please, you're not that kind of person.
Bernadette: I know. But if she orders something low-fat I'll totally give her the full-fat version.

Leonard: Uh, that's my water.
Sheldon: What?
Leonard: My water. You're drinking it.
Sheldon: Dear Lord! Have you been drinking it?
Leonard: Yes. It's my water.
Sheldon: Well, that's it then. I'm dead.

Leonard: Here we go.
Sheldon: I'm sorry, do I really need to connect the dots for you? The backwash into this glass is every pathogen that calls your mouth home, sweet home. Not to mention the visitors who arrive on the dancing tongue of your subtropical girlfriend.

Raj: Hey! That's my sister and my country you're talking about. Leonard may have defiled one, but I won't have you talking smack about the other.

Bernadette: You guys ready to order?
Sheldon: Yes, Id like a seven-day course of penicillin, some, uh, syrup of ipecac to induce vomiting, and a mint.

Leonard: That's actually my napkin.
Sheldon: Oh, this is a nightmare!
Howard: Where are you going?
Sheldon: To the bar, to sterilize my mouth with alcohol. Gangway, dead man walking!

Bernadette: All right. Here you go. Two lemonades, one iced tea and a root beer for Priya.
Priya: Is it diet?
Bernadette: That's what you ordered.

Leonard: Howard and his mother are at the hospital. Come on, we gotta go.
Penny: Oh, my God! What happened?
Leonard: I don't know, I just got a text. Come on, hurry.
Penny: Okay.
Leonard: Sheldon, let's go!
Sheldon: To a hospital? Full of sick people? Oh, I don't think so.
Penny: Okay, well, your friend and his mother are there, we're going.
Sheldon: I can't.
Penny: Oh, don't tell me you're afraid of germs.
Sheldon: Not all germs. Just the ones that will kill me. It's the same way I'm not afraid of all steak knives, just the ones that might be plunged in my thorax.
Leonard: Right, fine. I'll tell Howard you didn't come because you're more concerned about your own well-being than his.
Sheldon: I would think he would know that.

Leonard: What did your mother say when you told her you were getting married?
Bernadette: He hasn't told her yet. He's waiting for the right time.
Howard: I was thinking of weaving it into her eulogy.

Sheldon: Fire demon.
Raj: Ooh, fire demon. Sheldon's turning up the heat.
Howard: Troll master.
Raj: Check it! Howard pulls one out from under the bridge. Nice!
Leonard: Water nymph.
Raj: Oh, yeah, she's got puddles in all the right places.
Sheldon: Could you please play the game without commenting on every card?
Raj: Sorry. Walking tree.
Sheldon: Last one.
Raj: I'm taking a stroll and I'm sporting wood.

Howard: Okay, the Eagle has landed.
Leonard: What's going on?
Howard: Bernadette and my mother are having a get-to-know-you lunch at the Old Town Deli.
Raj: Oh, that sounds lovely.
Howard: Hope so. Of course, if history is any indication, my mother will swallow her whole and spit out her bones like an owl.

Leonard: Have you met Bernadette's parents?
Howard: You mean Adolf and Eva? Not yet. One goose step at a time.

Howard: Ma, I'm home! Where are you?
Mrs. Wolowitz: I'm in the toilet.
Howard: So, how'd it go?
Mrs. Wolowitz: Too soon to say. I'm not done yet.
Howard: No, I mean lunch, today, with Bernadette.
Mrs. Wolowitz: Oh! I had a pastrami sandwich. She had eggplant lasagna. Like that's what a person orders in a Jewish deli.

Howard: Besides food, did you get along? Did you talk?
Mrs. Wolowitz: Oh, sure. Did you know she's going to school to become a microbiologist?
Howard: No, she never mentioned it.
Mrs. Wolowitz: I bet she did and you didn't listen.

Howard: So, what do you think? Do you like her? She's great, huh?
Mrs. Wolowitz: She's a lovely girl. Cute as a button.
Howard: That's good to hear, 'cause I've got some news.
Mrs. Wolowitz: I hope it's good news, because I've got nothing but disappointment in here!

Sheldon: So your mirth is merely a discharge of nervous energy with no semantic content at all?
Penny: My mirth. Classic.
Sheldon: Is there a station coming up where I can board your giggling train of thought?
Penny: It's not a big deal, Sheldon. It's just, ever since Leonard's been dating Raj's sister, I've had to keep my distance. I don't get to hear all your jibber-jabber.
