Bernadette: Since when do you work on weekends?
Raj: I'm an astrophysicist. The stars don't take a day off.
Penny: You were home alone and had no one to play with?
Raj: Well, the cleaning lady was there, but she doesn't like me.

Raj: Okay. Would you ladies please leave the room for a moment?
Penny: Why?
Raj: I need to rub my genitals on their prototype.
Bernadette: What's going on?
Raj: Leonard and Howard dont have a flat. They went to the movies. Look.
Penny: Un-freakin' believable.
Bernadette: Son of a bitch!

Amy: It's okay, Sheldon. You know, I've saved a lot of weird things, too.
Sheldon: Like what?
Amy: Well, um, did you know I have a microscope slide with a little bit of tissue from the first brain I ever dissected?
Sheldon: I have an old teddy bear I secretly wiped my nose on for years.
Amy: It's not a contest.

Penny: Okay, here they come.
Bernadette: Go hide.
Raj: Oh, man, when I come out of the closet, I'm gonna nail those guys! Yeah, I heard it. Shut up.

Raj: (Inside the closet) Don't forgive them. Stay mad at them.
Howard: What is he doing in there?
Raj: Busting you.
Bernadette: It's okay. They apologized.
Penny: Yeah, it's fine.
Raj: Well this is kind of anti-climactic.
Howard: You know what wasn't anti-climactic? The end of the movie. Get this.
Raj: No spoilers. No spoilers.
Penny: And he's back in the closet.

Sheldon: I suppose I should set this up. Or would you like to rob me of that, too?
Amy: Knock it off or I'll start making W-H sounds for words that just have a W.
Sheldon: You wouldn't.
Amy: Whatch me.

Amy: I didn't understand your e-mail.
Sheldon: Uh, can you repeat that? You're breaking up.
Amy: I didn't understand your e-mail.
Sheldon: Ah. Yeah, I had to get a little creative because the S, R and M keys on my laptop stopped working.
Amy: Deaw Aby, could you pleathe dwive be to the twain thtow thubtibe tobowow?
Sheldon: So, is that a yes?

Leonard: Soup, sandwiches and emasculation, just like my mom used to make.

Howard: You want to come with us?
Bernadette: I'm kind of getting into the groove here.
Penny: Yeah, you guys run to the store and let the women handle the science for a change.
Leonard: Okay. We'll be back as soon as we can.
Penny: (To Bernadette) Okay, so what is solder?

Amy: Will you please tell me where were going?

Sheldon: Sorry, you're on a need-to-know basis.
Amy: I'm driving the car. I need to know.
Sheldon: Right.
Amy: So where are we going?
Sheldon: No, I meant turn right, and you missed it. Maybe you do need to know.

Sheldon: Welcome to my Fortress of Shame.
Amy: I'm sorry. What, what am I looking at?
Sheldon: It's basically everything I've ever owned. Um, every book, every tee shirt, every piece of broken electronics. Just all of it.
Amy: All of it?
Sheldon: I have a Ziploc bag filled with all my old Ziploc bags.
Amy: Okay. Well, I would like to tell you that there is nothing here to be ashamed of. So I'm gonna need a minute.

Amy: Okay, why do you have a bin of pine cones?
Sheldon: I used to collect them as a child. The spiral of scales open in the Fibonacci sequence. A fact that, when you tell your brother, gets a golf ball thrown at your head.

Penny: So, hows it goin'?
Leonard: Good. Slow.
Howard: There's a lot of tedious setup, but once we get through that it should go quicker.
Penny: Is there anything we can do to help?
Leonard: You know what, this part isn't that technical. You actually could.
Penny: Wow, really? Called my bluff. All righty then.

Sheldon: Look at the 4K resolution. Next time we Skype, I'm gonna count all those nostril hairs.
Amy: Or you could just look into my eyes.
Sheldon: But you only have two eyes. You got a lot of nostril hairs.

Raj: Okay, that's cool. I guess everybody's involved in this project but me. So, see ya.
Bernadette: I feel bad. Should we have asked him to stay?
Raj: (From outside) Yes.
