Penny: I thought they fired you guys.
Sheldon: They did, but then they hired me back.
Leonard: Well, you better not be working on our project, because we're a team.
Sheldon: Leonard, there is no "I" in team. However, there is an "I" in "I'm working with the military and you're not." There's five of them, in fact.

Raj: Hey! Look what I got everybody.
Leonard: Newspapers? Did you find a portal back to the 1990s?
Penny: No. If he had that, he'd be trying to prevent NSYNC from breaking up.
Raj: Oh, please. I'm glad they broke up. Otherwise, Justin would never have brought sexy back.

Penny: Oh, uh, hey, Beverly, you called my phone, not Leonard's.
Beverly Hofstadter: Actually, I was hoping to speak with you. Is this a good time?
Penny: Uh, that depends. What time is it where you are?
Beverly Hofstadter: Uh, just after 5:00.
Penny: (clears throat, and swaps fruit juice for a bottle of wine) Yeah, that counts.

Amy: Okay, how do you want to play this? Do you want to pretend like nothing's bothering you and blow up later, or do you just want to be a maniac right now?

Amy: What's with the blinking?
Sheldon: It's Morse code. So we can talk about without hurting --'s feelings.
Amy: Sheldon, I don't know Morse code.
Howard: I do. And if you have something to say, you can say it to my face.

Howard: Do you think Zack stole it?
Penny: No, he doesn't know how to steal Bitcoin. I mean, he waves at trucks.

Wil Wheaton: Hello, Sheldon. I suppose you've come here to tell me that you've moved me to your super secret enemies list.
Sheldon: I don't have a super secret enemies list. I'm not a Bond villain. I'm just a regular guy, with a regular enemies list.

Sheldon: I can't believe you don't care.
Professor Proton: Believe it.
Sheldon: Well, I care, a lot, and Wil Wheaton will rue the day he ever met me.
Professor Proton: I think that's true of most people.

Penny: Boy, you know, when Sheldon sees you in that dress, he's gonna want to methodically take it off, fold it up, carefully place it in a storage box, label it, and then ravish you.

Bernadette: But then we realized that it's a gift, in the sense that we didn't ask for it, and we may not have chosen it-
Howard: And we already have one.

Penny: Hey, I thought you were coming right back.
Leonard: I was, but we're both depressed, and decided to drown our sorrows.
Penny: With mouthwash? Man, that is so summer camp.
Sheldon: It's Romulan ale, from Star Trek.
Leonard: It was briefly legalized during the alliance between the Romulan Empire and the Federation at the time of the Dominion War.
Penny: Aw, now I'm depressed.

Howard: Oh, did your mom pack your lunch?
Sheldon: (chuckles) Of course not. Do you know how much it costs to pack a tuna fish sandwich in dry ice and overnight it from Texas? Well, I do, and my mother says it's too expensive.

Raj: This baby's got a ten-inch diameter with f/10 ACF optics.
Howard: And tonight Mercury is at its highest elongation.
Sheldon: It makes far-away things seem close, and Mercury is a planet.
Penny: I know Mercury is a planet. But the-the other thing was helpful.

Amy: That was Wil Wheaton. He's really excited about tomorrow.
Sheldon: As am I. If you'd have told me as a child that an actor from Star Trek would be officiating my wedding, I would've said, "Ooh, William Shatner?" And if you'd have said, "No, Wil Wheaton," I'd have said, "Well, did you even try William Shatner?" And if you'd have said, "Yes, but he costs too much money," I'd have said, "Ah, well, Wil Wheaton's good, too."

Penny: Amy, oh, my God.
Bernadette: You look so beautiful.
Amy: I feel beautiful. And look, both clavicles. Take that, Mom.
Bernadette: You know what they say: if you got 'em, flaunt 'em.
