Bernadette: Well, she's nine months old, so unless it jingles or is in my bra, she doesn't care.

Raj: I like tuna fish.
Sheldon: Do you want it? I'll sell it to you for $5,000.
Leonard: How's the fundraising going?
Sheldon: Oh, that depends. Raj, was that a "yes"?
Raj: No.
Sheldon: It's going badly.

Leonard: Okay, that's enough. This fight either has to end or get way more entertaining.

Amy: I think I'm just gonna go over here and sit on the couch.
Sheldon: Oh, great. Then we will move on to stage two: the pitching of woo.

Raj: I want you to know, I did what you asked. I talked to Ruchi and found out what's going on at work.
Bernadette: So is she trying to steal my projects?
Raj: No, not trying to, sounds like it's a done deal. Here, have a brownie.
Bernadette: I'm gonna kill her.
Raj: Okay, don't take this out on Ruchi. Is she trying to take your job? Yes. Is she parking in your space? Yes.
Did she get a laugh at a meeting yesterday by calling you "Pregnadette"? Big one. But you would've done the exact same thing, and you know it.

Howard: Are you gonna help me or not?
Raj: No, I will not help you. (sighs) But I will help Halley. She's my goddaughter, and I love her. And I have a lot of party favors left over from Cinnamon's birthday, so I hope she likes things that squeak when you chew on them.
Howard: Sh-She's a human being, not an animal. But that actually would be a hit.

Sheldon: Ordinary people can't beat a casino, but mathematicians and scientists, they do it all the time. Yeah, a group of students from MIT took Las Vegas for millions, and that's MIT. Howard went there.
Howard: Come on, Sheldon. I'll give you a ride out to the desert right now.
Leonard: No one is going to Vegas.
Howard: No, we weren't gonna make it to Vegas.

Leonard: Edison was kind of a publicity hog and a bully.
Raj: Yeah, he electrocuted an elephant named Topsy just to make himself famous. If I had an elephant named Topsy, he would want for nothing. Also, he'd be named Jumbo.

Bernadette: Hey, what are you two doing here?
Ruchi: We won't stay long. I just wanted to drop something off from me and the girls at work.
Bernadette: None of the girls at work like me enough to get me a gift.
Ruchi: Okay, so you'll know why everyone at the office has the same handwriting.

Howard: Hey, I barely know how to be a man myself. Now I have to teach someone?
Sheldon: Well, as the saying goes, those who can't, teach.

Penny: Uh, well, both of our jobs are going great.
Leonard: Sure. I mean, my Air Force project got taken away, and you're not crazy about selling pharmaceuticals. I'll just write down "still employed."

Sheldon: Leonard, can you drive me to work?
Leonard: Yeah, sure. Oh, hey, the guys and I were talking about going to see the Tesla coil at the observatory later on, if you want to join.
Sheldon: Oh, I'm sorry, I can't. I'm busy.
Leonard: Why? What are you doing?
Penny: Leonard, what are you doing? He said he can't go. Make a sad face, move on.

Penny: You know, that documentary last night was actually better than I thought it would be.
Leonard: Really? Should've been about Samuel Morse the way they telegraphed that ending.
Penny: I already pretended to laugh at that joke once. Do I have to do it again?
Leonard: Yeah, I'd appreciate it. (chuckles)
Penny: (forced laugh) Samuel Morse. You kill me.

Sheldon: Well, I hope you're hungry.
Amy: Oh, I'm starving.
Sheldon: Oh, good. Starvation is authentic to the time period. If you also have malaria and a deep distrust of Native Americans, we're really cooking with a woodstove.

Howard: So how was your night with Ruchi?
Raj: Oh, great. We ordered in some food, we had sex, I left. I didn't even ask if she enjoyed it.
Howard: (chuckles) I can field that one for her.
Raj: I mean, I did get a little misty when we said good-bye, but I played it off as allergies. I don't know if she bought it.
Howard: Again, I know.
