Doctor Wolcott: Yeah, I'm a married man myself.
Leonard: Oh, really? Is she here?
Howard: And alive?
Raj: And can people other than you see her?

Doctor Wolcott: Dr. Cooper, if you can promise me these men share your intellect and academic rigor, yeah, I suppose they can join us.
Sheldon: You guys might need to wait in the car.

Sheldon: Well, of course I'm worried about you, I want you to be safe.
Amy: And I want you to be safe.
Sheldon: I will be. I'll have my friends with me. If anything should go wrong, I can use them as human shields.

Sheldon: *knock knock knock* Dr. Wolcott? *knock knock knock* Dr. Wolcott? *knock knock knock* Dr. Wolcott? [sound of many locks clacking]
Howard: That's a lot of locks.
Leonard: Mm. That was a lot of knocks, they were made for each other.

Doctor Wolcott: Well, let me show you around. This is the chair where I do most of my thinking, my thinking about work. Now, my thinking about people who have wronged me, I do over there.
Sheldon: I've always said that I should get a grudge chair. Leonard, have I not always said that?
Leonard: Mm, you have, but you were worried you'd spend too much time in it.
Sheldon: Yeah. That is a real concern.

Sheldon: Do you really know how to Riverdance?
Amy: You tell me.
Sheldon: I'm the only man you do that for.

Raj: Oh, my God, this tomato is amazing! I can eat it like an apple.
Doctor Wolcott: My secret is I fertilize it with my own manure.
Howard: The look on your face.
Leonard: It's a sort of grin. You want to know what kind?

Howard: That's great, everyone's got weekend plans. Amy has her bachelorette party, and Sheldon's gonna go to the woods and get hunted for sport.
Penny: Yeah, as someone who has to track him every time he gets lost in IKEA, I feel like I'd be really good at that.

Sheldon: But maybe you could drop me at the bottom of the mountain. I want him to think I'm cool.

Sheldon: Do you have any mail for Dr. Sheldon Cooper?
Mailman: I do, but I can't hand it right to you. I have to put it in the box.
Sheldon: And that is what separates the U.S. Postal Service from those hippies at FedEx.

Sheldon: Oh, he's invited me to his cabin for the weekend, to discuss a breakthrough he's had.
Howard: His cabin?
Sheldon: Yes. He lives off the grid, up in the mountains.
Leonard: So you're gonna go to the middle of nowhere and spend the weekend with a crazy man you've never met?
Sheldon: Yes. Why?
Leonard: No reason. Have fun.

Amy: Sheldon, what are you doing?
Sheldon: I am decoding Dr. Wolcott's letter using this book as the key. Aren't conversations more fun when they're in code?
Bernadette: Yes. But I'm using a code where "yes" means "no."

Leonard: Don't look at me. When the music stopped, you were holding Sheldon.

Amy: Are you sure you're gonna be okay this weekend?
Sheldon: Of course. No, I'm much more concerned about you. I know how you gals behave when the men are away.
Amy: You do?
Sheldon: I've read The Bacchae by Euripides. Drinking wine, riding panthers Proof that girls have gone wild for over 2,500 years.

Amy: I'm sure there'll be some drinking and some dancing, and then a mailman'll probably show up and take his clothes off-
Sheldon: Nicholas is going to take his clothes off?
Amy: No, not our mailman. A dancer pretending to be a mailman.
Sheldon: Impersonating a federal employee? Oh, where's the after-party, prison?
