Sheldon: I may have lost my guidance system and my girlfriend, but I still have a colon full of yesterday's meals to keep me company. Although, thanks to your high-fiber breakfast, I'm sure that'll be leaving me, too.

Bernadette: It's okay, I'm just being emotional about this. Can you not tell Howard?
Stuart: Well, don't you think it'd be healthier if you told him what's going on with you?
Bernadette: Don't you think it'd be healthier if you had your own apartment, grown man?
Stuart: Your secret is safe with me.

Lucy: Can I just say something? Going out with Raj was one of the best things that ever happened to me.
Raj: Yes, I'll take you back.
Lucy: It's like I needed to go through that experience to know what exactly I don't want in a man.
Raj: That's hard to hear, but I'll still take you back.

Bernadette: Not every girl dreams about being a mom. Sometimes you think you're never gonna have kids and one day you wake up and you're pregnant. And it doesn't matter that your career's going great right now and that you and your husband never even got to go anywhere taped to a dog!

Penny: Not only did they eat together, Leonard said he made her laugh.
Bernadette: That's nothing, Howie said she touched his hand.
Penny: Did he Purell?
Bernadette: No.
Penny: I cannot believe Leonard mentioned the Toblerone but left that part out.

Leonard: Penny's gonna call her dad and tell him it's not a good time for Randall to visit.
Penny: Hopefully, he won't be too upset.
Leonard: Oh, you're his little girl. He can't stay mad at you.
Penny: He won't be mad at me. I mean, you're the one who doesn't want my brother to come, so-
Leonard: So you're gonna throw me under the bus?
Penny: Oh, I'm gonna throw you so hard, I might actually win a stuffed animal.

Sheldon: So Bernadette, if I express interest in your baby will you promise not to make me touch it?
Bernadette: Sure.
Sheldon: Hey, how's life with your baby?
Amy: Really? You're never gonna touch their baby?
Sheldon: To this day I've never touched Stuart.

Sheldon: I am not proud of this. But I have been envious of your recent success.
Bert: Wow, I won the MacArthur Grant, everyone's jealous of me. Once I get LASIK, I'll be out of things to wish for.

Penny: All right, this is making me crazy. Somebody's got to go over there.
Leonard: You got feet and legs, you do it.

Sheldon: Why would she keep something from me, you know? I shared my body with that woman. And my Netflix password. They recommended "Stella Got Her Groove Back" because of her.

Sheldon: How much will it hurt?
Amy: It's just a tiny skin sample. You saw me do it to myself.
Sheldon: On a scale of one to ten, where one is a pebble in your shoe and ten is the monkey you thought was your pet biting your face off.
Amy: A two.
Sheldon: Eating a whole Altoid?

Bernadette: Uh, I left my phone downstairs!
Howard: Damn, so did I.
Bernadette: Wait, I have my iPad.
Howard: What are you going to do, e-mail 911?

Sheldon: He also has a remarkable amount of credit card debt.
Howard: I thought your dad paid your cards.
Raj: I have a card for emergencies that I pay for myself.
Sheldon: What emergency happened at the L.A. Zoo?
Raj: That's a penguin I sponsor. They're losing their homes to global warming, and my car gets, like, seven miles a gallon, so I felt bad.

Leonard: Okay, so this is the main Comic-Con floor. It's where all the vendors and exhibits are.
Penny: Wow, that is a lot of people jammed in there.
Leonard: I know. Sometimes Howard wears a striped shirt so we can play "Where's Wolowitz?"

Bert: Okay, well, thanks for coming by. You're nice people.
Penny: Well, so are you. In fact, you know what? We will never take you for granite. Did you get that? Granite? A little geology joke.
