Howard: You know, maybe before our meeting we should talk to a lawyer.
Leonard: That's not a bad idea.
Raj: Well, you must have someone in your family that's a lawyer.
Howard: Why? Because I'm Jewish? That's like me saying, "Hey, you're Indian. Doesn't your cousin work in a call center?"
Raj: My cousin does work in a call center.
Howard: And my cousin's a lawyer.

Amy: I've been smacking that ketchup bottle for a long time. All she has to do is tip it over and point it at her fries.

Sheldon: My pants are missing, I don't remember anything. Penny, this is your youth. What do I do?

Amy: Listen, you and I are gonna be sharing a bed. You know, this is uncharted territory for both of us. How are you feeling about that?
Sheldon: Oh, excited, concerned, a little scared. All the same emotions I feel in line at Space Mountain.

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.

Sheldon: No matter where I am, this will always be my spot.

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.

Amy: Sheldon, that's enough.
Sheldon: Oh, yeah, no, fine. Let's just agree that both creations are special in their own way and it is foolish to try and compare them. Although, we didn't need to have sex with Howard for ours, so we win.

Amy: Comfy?
Sheldon: Oh, I'm just happy I don't know what this memory foam remembers.

Penny: Oh, that's a nice offer.
Zack: You know, we'd make a great team. Or as we say in the menu business, I can't do this without Me N U.
Penny: Right, 'cause it spells "menu."
Zack: Yeah, right? It's funny. I got a lot of menu jokes, but that's my favorite.

Stuart: Nice to see you again, Dr. Hofstadter. I'm, uh, Leonard's friend, Stuart.
Beverly Hofstadter: Nice to see you, too.
Stuart: Hi, I'm Stuart.
Alfred Hofstadter: Ooh, I'm Alfred, Leonard's father.
Stuart: Oh! Oh, hi. Uh, I'm sorry, did you two want to sit together?
Beverly Hofstadter: No!
Alfred Hofstadter: No!
Stuart: I was wondering why the front row was available.

Penny: Uh, what's new?
Zack: Oh, tons of stuff. Put artificial grass in my backyard, got engaged, had a scary mole that turned out to be Sharpie.
Penny: Well, congratulations.
Zack: That's what my dermatologist said.
Penny: No, on getting engaged, good for you.
Zack: Oh, thanks.

Bernadette: Anybody have anything snarky to say about that? Didn't think so.

Raj: Yeah, this military guy showed up at Howard's door. He was terrifying.
Sheldon: Oh no, what did he say?
Raj: He gave me his business card and asked me to please pass it along to Howard.
Sheldon: That doesn't sound terrifying.
Raj: Not to a white guy born here, no. To a brown guy whose name has a lot of syllables in it - terrifying.

Sheldon: We don't need Howard's cousin, no. We have me.
Leonard: You're not a lawyer, Sheldon, you're just a know-it-all.
Sheldon: I am not a know-it-all. I'm a person who knows lots of things and likes to correct other people when they're wrong.
Leonard: That's the definition of being a know-it-all.
Sheldon: Or in German, a Besserwisser.
