Howard: You know what? Forget the past. What do you say you and me build this rocket?
Sheldon: That sounds like it could be a real bonding experience for us.
Howard: Right?
Sheldon: Oh, I see. Oh, you think that's a positive.

Leonard: Would you ever get a vasectomy?
Raj: Uh, in case you haven't noticed, Indians aren't too big on birth control. There's probably, like, a million more of us since we started this conversation.

Leonard: Okay, the next drug is Romatrol.
Penny: Oh, I know this one. We're actually pushing it really hard. It treats mild dermatitis.
Leonard: Uh, correct. And who can it be prescribed to?
Penny: Adults and children who have absolutely, for sure, stopped growing.

Raj: What if the reboot is great?
Sheldon: That's even worse. If-if I like it, I'll feel like I'm being disloyal to Arthur. He was a mentor and a friend, and I won't toss him aside for some Hollywood pretty boy like Wil Wheaton.
Raj: It's hard to argue with him.
Leonard: Because he makes no sense? Yeah.

Leonard: Isn't the important thing that there's a show to get kids excited about science?
Sheldon: Who cares about kids and what they like? This is about me and something I liked when ... when I was a kid.

Sheldon: Come on. How many times have we banded together to try to save a show that we loved? Let's shake things up and try to kill one.

Sheldon: We're engaged.
Raj: Oh, my God, that's amazing! Wait, uh, tell me everything.
Sheldon: Well, Dr. Nowitzki was kissing me-
Amy: Okay, you can stop leading with that part of the story.

Penny: All right, so what are we celebrating?
Leonard: Well, you know, Bernadette and Howard are pregnant again, and Amy and Sheldon are getting married. I didn't want you to feel left out.
Penny: Left out? Well, Bernadette has to grow a baby inside of her, and Amy has to marry one. My life is great.

Howard: [In Mandarin] This is Howard Wolowitz. We didn't get our fried rice. My fat Indian friend is upset. Thank you.

Mary: Thank you again for picking us up.
Raj: (chuckles) My pleasure, Mrs. Cooper.
Mary: You know, our driver to the airport was also a Indian fella.
Missy: Mom!
Mary: Oh, so now it's racist to notice when somebody's Indian.
Raj: I don't think it's racist. I noticed you were both white.
Mary: See?

Amy: I'm just saying maybe there's a part of you deep down that just wants to relax a little, you know? Kick back. Say, "Whatev."
Sheldon: Whatev? I'm sorry, you're really not gonna finish that word?
Amy: I'm just trying to make a point-
Sheldon: Finish the word, Amy.
Amy: Fine. Er. Er, er, er.
Sheldon: Thank you. Only now you owe me three more whatevs.

Leonard: Ms. Davis, you wanted to see me?
Ms. Davis: Yes, Dr. Hofstadter, come on in.
Leonard: Should I sit or stand? I'm not used to being called into the dean's office.
Ms. Davis: Please, sit.
Leonard: I have to say I'm a little nervous.
Ms. Davis: You should be.

Sheldon: Amy, there's something I need to say to you.
Amy: I'm listening.
Sheldon: I've been thinking about the Avengers.
Amy: I believe that. But I don't think that's something you needed to say to me.

Sheldon: Hmm who could it have been?
Amy: Sheldon, what did you do?
Sheldon: I plotted my revenge. If you get a dish, I'll serve you some cold.

Mary: Let me straighten your tie.
Sheldon: No, no, no, it's all right. It's supposed to be a little asymmetrical. Apparently, a small flaw somehow improves it.
Mary: I can see that. Sometimes it's the imperfect stuff that makes things perfect.
Sheldon: Excuse me. *Sheldon rushes out of the room*
Mary: Case in point.
