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

Leonard: I got it.
Howard: You really figured it out?
Leonard: No, but when we show this nonsense to Sheldon, it will make him crazy, and he'll have to fix it.
Howard: Oh, you're a genius.
Leonard: Yeah, I know. That's not even a math symbol. That's just Charlie Brown's hair.

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!

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?"

Amy: What are you looking at?
Sheldon: Comments from our Behind the Flags retrospective. Get this, people are calling it "the longest one yet".

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.

Raj: No offense to her father, but he's not an MIT-trained engineer. Thinking and building is what you do.
Howard: MIT's motto is "Mind and Hand," which just so happens was also my motto as a lonely teenager.

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.

Howard: Stuart, stop driving like an old man. Speed it up a little.
Stuart: I'm not an old man! I just can't see at night.

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: Oh, you know. The Lone Star state. That should be its Yelp rating.

Howard: I can't believe you made fun of me all these years while you were a closeted ventriloquist.
Bernadette: Okay, it's not like I wanted to be a ventriloquist. I was in beauty pageants and I needed a talent besides spreading rumors that the other contestants were pregnant.

Penny: Could you two really have some sort of super-intelligent child?
Amy: Well, there is a genetic component, but that doesn't guarantee anything.
Leonard: That's true. Sheldon's father once picked a fight with a cactus.
Penny: Yeah, but that's just his Earth parents. We don't know anything about the ones that sent him here.
Leonard: Well, we know they were smart enough to send him away.

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.

Penny: She said not to come. It's gonna be a while.
Amy: (sighs) Well, first deliveries can be slow.
Sheldon: I am starting to rethink the Flash onesie I bought this kid.
