Sheldon: What would you like me to say?
Leonard: How about congratulating us?
Sheldon: Are congratulations even in order? I didn't think Penny wanted children.
Leonard: Well, she didn't, now she does. And just so you know, we weren't gonna tell anybody so we wouldn't upstage your big day.
Sheldon: Oh, please, you couldn't upstage us. We won a Nobel Prize. Any idiot can have a baby.
Howard: Hey. What's going on?
Sheldon: Case in point.

Leonard: You are a selfish jerk. To hell with you and your Nobel Prize.

Raj: I found her boarding pass in her purse. It's totally her.

Howard: Oh, good, you're here. Listen, we're thinking maybe we should go back to L.A.
Amy: Why?
Howard: We just can't be this far away from the kids. Bernie's having a meltdown, and, frankly, so am I.
Sheldon: Yeah, well, pull it together. This is a big day for me.
Howard: [scoffs] Yeah, I wasn't sure what to do. Now I am. We're going home.
Leonard: We'll join you.
Penny: Oh, wait. Do I get a vote in this?
Leonard: They'll have pickled herring on the plane.
Penny: Bye-bye.

Penny: Okay, that's it for the fish. We'll be back with the meatballs after a short word from our sponsor.

Leonard: How long is it gonna take you to get ready?
Penny: Oh, I just need, like, five or ten minutes.
Leonard: Really?
Penny: No. What is wrong with you?!

Amy: Sheldon.
Sheldon: What? Did you finish? Great job.

Sheldon: Uh-oh. That's the fourth time she's been to the bathroom in the last two hours.
Amy: So?
Sheldon: Her breakfast was binding. I made sure of that.
Amy: So?
Sheldon: So she clearly has some sort of stomach distress. If it's viral, we're all susceptible.
Amy: She's probably just airsick.
Sheldon: Yeah, but what if she's not? What if we get what she has? What if we infect the King of Sweden? That's how wars start. [Penny leaves the bathroom and instantly heads back] All right, that's it, this is Outbreak and she's the monkey.
Amy: [faintly] Wait. Stop. Be reasonable.
