Amy: I'm in a secret club! Shh! Is there some sort of humiliating initiation? 'Cause I would literally do anything.

Amy: Sheldon, this isn't about ruing. This is about humbly accepting a great honor.
Sheldon: Amy, we won the Nobel Prize in Physics. Humility is for people who win the goofy Nobels like Literature, Economics and Peace.
Amy: Please tell me that's not in your speech.
Sheldon: Oh. I can cut it, but it's the only joke I have.

Leonard: Can't believe it. Sheldon loves telling on people when they break the rules.
Penny: Yeah, well, maybe he's changed.
Leonard: He hasn't changed. Last week, when the vending machine gave me two bags of chips, he called my mom.
Penny: Well, that didn't ruin your life.
Leonard: Well, it ruined my day. I had to talk to my mom, who, by the way, is-is polyamorous now, so that's fun to think about.

Barry Kripke: Leonard, I know you and I have a oh, troubled history, but I hope that when I make my request you'll give me a fair shot.
Leonard: Of course.
Barry Kripke: See? That's why I like about this guy: integrity. Bring it in! I just put something in your pocket. It's good at all El Pollo Locos.

Sheldon: Well, people used to call me egghead 'cause there were eggs on my head. 'Cause they threw them at me.

Bernadette: One time my brothers made me breathe helium. I tried to call for help, but the only one who could hear me was the dog.
Sheldon: That's also terrible. My goodness, you had to live in a house with a dog.

Barry Kripke: Hofstadter! Heard Siebert put you in charge of the administrative fund. Can't think of a better guy for the job.
Sheldon: I think he's done this before.

Sheldon: All right, well, we should head out now if we're gonna get to the airport six hours before boarding.

Penny: You know, if this woman's gonna be around, I think we should check her out a little. I looked online. She doesn't have an Instagram, which means she's either 80 or something's wrong with her.

Leonard: Uh, hold on, I'm not just gonna hand out money. There's a procedure you need to follow.
Sheldon: I believe he's referring to the traditional "kissing of the buttocks."
Howard: Should we form a line, or just do it like we're bobbing for apples?

Raj: Sheldon, you sure you're ready for this? This movie's pretty scary.
Sheldon: Please. I'm an adult. I think I can handle it.
Leonard: That's what you said about the butterfly pavilion at the zoo.
Sheldon: That was my fault. After I pet that goat, I felt like a gladiator.

Leonard: Well, Siebert put me in charge of handing out the last bit of the administrative funds, and I have sole discretion.
Raj: Ooh! Looks like Christmas came early. First thing on my list is a golden umbrella, 'cause Leonard's gonna make it rain!

Raj: Oh, this is amazing. I wish I had a playhouse like this when I was a kid.
Penny: Really? You never had a playhouse?
Raj: No. I mean, my dad did buy the house next door for us to play in.

Penny: Hey, want to get lunch?
Bernadette: I can't. Halley and Michael were up all night, and I'm way behind here.
Penny: Oh, no, are they sick?
Bernadette: No. They were just laughing and playing like a couple of jerks. Boy, they're cute, but they ruin everything.
Penny: I get that. You know, I've been thinking lately that maybe I don't want kids.
Bernadette: Are you crazy? Of course you want them. It's amazing.
Penny: You just said they ruin everything.
Bernadette: I'm allowed to. It's their fault I pee when I laugh.

Howard: I'm gonna hook up the garden hose, so it has running water.
Amy: Why does it need running water?
Howard: Same reason it's got electricity: Bernadette and I both work, and we're overcompensating.
