Raj: Okay, so, what it sounds like is, what we want is a device that can deliver a message through not only sight, but other senses, as well.
Leonard: The most basic sense that any space-faring civilization would have to possess is touch.
Raj: Ooh. Ooh, ooh! We could make a video-playing device that simultaneously translates the information into a tactile medium.
Leonard: All we have to do is rig up a 3-D communication system!
Raj: We-we can totally do that!
Leonard: I know!
Raj: This is great!
Leonard: Yeah, you know what else it is?
Raj: What?
Leonard: Exactly what Sheldon and Howard said.
Raj: Well, thank you for peeing in my slippers.

Howard: You don't think I'm a leader?
Bernadette: I was kidding. Of course you are.
Howard: Right. I couldn't change if I wanted to.
Bernadette: You better not change, because I love who you are. Now, will you need help cleaning all this up when you're done or can you do it all by yourself?
Howard: All by myself.
Bernadette: There's my big boss man.

Sheldon: Greetings from Planet Earth. Just turn left at Alpha Centauri. You can't miss it.

Alien: That soft pink alien looks delicious. I could eat.
*Sheldon performs Vulcan salute*

Sheldon: Now, we can play this one of two ways. You can say, "Trains! Tell me more," or, you can just look at me like that and I'll start.

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

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.

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.

Sheldon: Perhaps Howard meant passive-aggressive like asking our group to help on your project, and then only choosing Leonard.
Raj: Look, I'm sorry I hurt your feelings, but you do have strong personalities and always end up taking over.
Howard: It's not always.
Leonard: What about when we went to Comic-Con and dressed like Jabba the Hutt? You got to be Jabba's head, and I got to be his fat slug butt.
Sheldon: We looked great.
Leonard: You let a guy sit on me.
Howard: He was dressed as Princess Leia. It made a nice picture.

Amy: I can't believe you got up and walked out of an audition for a big movie.
Penny: I did. I mean, I walked in, read for the part, then stunk up the place, but then I walked right out.

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.

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?

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.

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: 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.
