Sheldon: Oh dear lord. Oh dear lord.
Amy: It's okay. We made it. We're fine.
Sheldon: That was a lot of puppies.

Leonard: Congratulations. Who would've thought you two would be the first in our group to start a family.

Penny: If you were to die this evening with no opportunity to communicate with anyone, what would you most regret not having told someone?
Sheldon: So it would be today? Huh. Well, I suppose there's something satisfying about dying on my birthday.
Penny: Today's your birthday?
Sheldon: Yes.
Penny: Well that's always been a secret. Not even Amy knows.
Sheldon: Well, I don't enjoy presents. And the thought of people jumping out and yelling surprise fills me with more dread than the words "George Lucas Director's Cut.

Leonard: We spent $200 on six minutes of fun.
Raj: It's like when we bought that remote-controlled helicopter and it just flew away.

Emily: There's one downtown where they trap you in a room with a zombie.
Raj: Oh, so kinda like what's happening with Penny right now.

Howard: Are you kidding me? You lost my mother's ashes?
Airline worker: No, I'm just saying that sometimes bags are misrouted.
Howard: All right, where did you misroute the only woman who ever loved me? The first woman - I meant first.

Raj: Given the choice of anyone in the world, who would you want as a dinner guest?
Leonard: I can honestly say Penny.
Amy: Aww, then I choose a janitor, because I'm about to throw up.

Penny: Raj, would you ever try an experiment like that with Emily?
Raj: I don't need science to win her heart, I have my family's wealth for that.

Raj: Hang on. If you're really Nathan Fillion, what's the line from Firefly about your bonnet?
Customer: I swear by my pretty floral bonnet, I will end you.
Leonard: That's it. That's the line.
Raj: Although, I knew the line, doesn't make me Nathan Fillion.

Leonard: If he's not nice, it's gonna make it hard for me to watch him in anything again.
Raj: The guy who plays Jon Snow was a jerk, we still watch Game of Thrones.
Leonard: He was a jerk because you rear-ended him.
Raj: I was distracted. It's weird seeing a member of the Night's Watch with a kayak strapped to his car.

Howard: That is a good point. But I didn't marry you for good points. I married you to blindly support me no matter how ridiculous I'm being.
Bernadette: This is why I had to rewrite our wedding vows.

Bernadette: Well, you've been living here a while now.
Stuart: I know. I may sell comic books at work, but the real superheroes are sitting right in front of me.
Bernadette: Yeah...
Howard: His middle name is David. Go.

Howard: Is there anything I should know before I go in?
Raj: Like what?
Howard: Like am I dressed okay?
Raj: Really? So every other place you've been, you thought this was fine?

Sheldon: I shouldn't have asked so many questions.
Penny: No, it's okay.
Leonard: Yeah, maybe it's good you got us talking about this stuff.
Sheldon: Well, look at that. Even when I'm causing problems, I make the world a better place.

Howard: As a scientist you believe the way to understand the universe is through facts and evidence. And now you're counting on some blue chick with a hundred arms to help you?
Raj: That is so offensive. Does everything you know about Hinduism come from Indiana Jones?
Howard: No, there's also Apu from The Simpsons.
