Mrs. Fowler: I can't believe it. All this time I've been angry at you when I should have been angry at Amy.
Sheldon: Look at that. We're both angry at Amy. Maybe that's something we could bond over. Let me ask you this: how do you feel about Howard?
Mrs. Fowler: Oh, is he that odd little friend you have with the haircut?
Sheldon: I may have married the wrong Fowler.

Bernadette: Why don't you want to work with me? I know I can be tough, but that's just 'cause I'm surrounded by useless idiots.

Howard: William Shatner, Kevin Smith. Who else could be there?
Leonard: Do you see what I see over his shoulder?
Howard: Is that a ghost?
Raj: I think it's Stuart.
Sheldon: That is Stuart. What-What's he doing there?
Raj: Maybe he died in Wil's house and he can't leave until he solves his own murder.

Sheldon: Leonard we need to do something about your wife.
Leonard: What's the matter?
Sheldon: She is clearly sick, and she's gonna take us all down with her.
Leonard: She's not sick, Sheldon.
Sheldon: She is, and I'm gonna catch it, and it's gonna ruin the greatest day of my life.
Leonard: I promise you're not going to get what she has.
Penny: What's going on?
Sheldon: [gasps] Unclean! Unclean!
Penny: What?
Leonard: He thinks you're sick.
Penny: Oh. Should we tell him?
Leonard: Well, if we don't, he might try and jump out of the plane.
Penny: Yeah. Doesn't answer my question.

Tour Guide: And here we have the former hotel where Tesla perfected the three-phase alternating current motor.
Sheldon: That's wrong. I'm gonna say something.
Amy: Don't.
Sheldon: Well, then how will everyone know I'm the smartest boy here?

Sheldon: It's so funny, we did all these experiments on them and they didn't even notice.
Amy: I know, I was worried it would be obvious, but it wasn't.

Amy: Let's just go to sleep. We'll look at it in the morning with fresh eyes, and maybe it'll come to us.
Sheldon: Fine.
Amy: Or we go tear apart that box and look for a clue.
Sheldon: Staying up past my bedtime and solving mysteries? Who knew married life could be this good?

Howard: Wow. I wonder what that guy could've done to make Sheldon not talk to him for 20 years.
Leonard: I wonder if it'd work a second time.

Raj: I came here for your support.
Leonard: Well, then, you just walked up three flights of stairs for nothing.
Penny: Wait, don't you mean four flights?
Leonard: No, it's actually three.
Penny: But we're on the fourth floor. I mean, you have the lobby, first floor, second, third, fourth.
Leonard: The lobby's the first floor, so lobby, second, third, fourth.
Penny: That does not seem right.

Leonard: Don't make it sound childish. It's the scientific word for dust.
Penny: What was wrong with "dust"?

Bernadette: Look at Howard. He was a disaster when I met him. Now he's a foxy astronaut with a hot wife.
Raj: Wait, he always wanted to be an astronaut.
Bernadette: He thinks that, too. That's how good I am.

Amy: Whatcha doin'?
Penny: You scared me.
Amy: I'll ask again. What-cha doin'?
Penny: Nothing.
Amy: Really? You and Bernadette aren't doing stuff without me?
Penny: What? No! Why would you even say that?
Amy: You know how your talent is getting just drunk enough to have a good time without being hungover the next day?
Penny: Thank you.
Amy: Well, mine is knowing when I'm being excluded.

Sheldon: Yes.
Leonard: Uh, I'm Leonard Hofstadter. I called you about the apartment. You said-
Tam: Tell him to go away. You already have a roommate.

Raj: Recently, 12 new moons were discovered orbiting Jupiter, bringing the total up to 79.
As a middle child myself, I'd like to extend my sympathies to moons two through 78. Your grandpa will never learn your name. I'd like to thank you for joining me on this journey through the stars. If you enjoyed this lecture, please come back Thursday for the exact same one.

Amy: Really, Sheldon? You want to do it again?
Sheldon: Don't act surprised. It's clearly marked on the schedule. Now, shall we steam the wrinkles out of our wizard robes, or make vigorous, socially sanctioned love? Either way, I can check something off my to-do list.
Amy: [reading Sheldon's to-do list on his phone] Socially sanc-- Oh, wow. Yeah, there it is right there.
