Raj: Look. I know you guys are upset, but we've talked about it and we think it would be beneficial for you to be part of the project.
Howard: Well. Well. Well. Did you hear that Sheldon?
Sheldon: I'm sorry. I was trying to think of what rhymes with Nose of the Aardvark.

Sheldon: Clearly, good things happen when I'm in charge. Now, why don't you boys step aside, let me knock this project out.
Leonard: Sheldon, you're not in charge. Raj is in charge.
Sheldon: Leonard, who's really in charge? The person in charge or those who put him in charge.
Raj: He's right. If you think about it, we're all in charge.
Sheldon: No, the guy in charge is in ch-. Why is everyone so bad at these?

Sheldon: Hey, would you like to hear some songs I've rewritten to get children interested in the hard sciences?
Howard: Sure.
Leonard: Really?
Howard: Yeah. I like music. I like science. I like making fun of Sheldon. Hit it!

Sheldon: Anyway, if you're looking for Leonard, he's with Koothrappali.
Penny: No, actually, I came to talk to you.
Sheldon: How nice!

Sheldon: So, often on the front of the locomotive is a large iron wedge for clearing objects off the tracks. Now, while commonly known as a cowcatcher, I prefer the more accurate "cow exploder."

Raj: Okay, so we know that previous attempts to send a message into space, like the Golden Record on Voyager, were heavily criticized.
Leonard: Well, aliens could only play the Golden Record if they figured out how to build a record player.
Raj: Eh. Although, to be fair, I watched E.T. build a telephone out of a Speak & Spell and an umbrella. Dude was like a little brown MacGyver.

Leonard: Now that we're all on the same page, let's get together tonight and work on it.
Sheldon: Get together tonight? Leonard, stop trying to control everything, and give poor Raj a chance to come up with what we should do. Go ahead, Raj.
Raj: Okay, I think we should do it right now.
Sheldon: Tonight works better for me.

Penny: *thinking* Okay, it's just an audition. Why am I nervous? Maybe it's a good thing. Just means I want it. And I can have it. This feels right. Why did I ever give this up? *opens door and sees room packed with women reading scripts* *speaking quietly* I'm starting to remember.

Penny: I mean, the whole experience reminded me about how much I hated about that world. You-you know, the anxiety, the depression, the negativity. I don't want to feel those things. I want to sell drugs to people who feel those things.

Penny: If I was at a train station and one train could take me to my current job and the other train could take me to an audition for a movie, which train should I get on?
Sheldon: Are you using trains to trick me into giving you advice?
Penny: No.
Sheldon: All right then. You should take a third train where you audition for the movie, but hold off on making a career decision until you have more information.

Leonard: Some times Raj and I feel pushed aside.
Raj: Yeah. Like when you took Sheldon to Texas and showed him all around NASA. You didn't even think to ask me and Leonard.
Howard: You know what, you're right. I should have asked you.
Sheldon: And if he does ask you, go. It's amazing.

Howard: Now if we're talking about being left out, you guys went to Skywalker Ranch without us.
Sheldon: Oh, I recommend that too. That was a magical experience.

Leonard: Wait a minute. Sheldon spent a whole day with James Earl Jones and never told any of us.
Sheldon: I sure did. My goodness. From Jabba's head to ice cream with Darth Vader, I'm having a heck of a ride.

Bernadette: I'm glad you have a new appreciation for you job.
Penny: I do. And you know, I don't think I've ever thanked you properly for helping me get it.
Bernadette: Properly? At all? It's just words I've never heard.

Bernadette: Now you're making some real money, maybe you can take your friend out for a nice thank you dinner.
Penny: Sure.
Amy: And you probably have to invite your other friend because she overheard you talking about it and it would be awkward to exclude her.
Penny: Yeah, okay.
Bernadette: How about now?
Penny: All right.
Bernadette: Don't forget your wallet.
