Penny: Is everything okay?
Bernadette: Look, I'm gonna tell you something, but you can't freak out, because I'm already freaking out.
Penny: Oh, my God, what is it?
Bernadette: I'm pregnant again.
Penny: (excitedly) Wha-? ... (quietly) Interesting.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?
Penny: Yeah, if he's in the room when they're making the baby, I'll give you $10.

Penny: I mean, who even reads Scientific American?
Leonard: It's kind of a big deal.
Penny: If it's such a big deal, how come the biggest celebrity they could get for the cover is a molecule?

Sheldon: I've thought about it, and I really want to spend the rest of my life with Amy. Do I have your blessing?
Stephen Hawking: Well, Sheldon, I think you should make her finger like Saturn and put a ring on it.

Sheldon: Wait, oh, and I just I want to let you know right now that we are not getting married in a church.
Mary Cooper: That's all right, Sheldon. Anywhere Jesus is is a church.
Sheldon: Well, he won't be at our wedding.
Mary Cooper: He's in my heart, so if I'm there, he'll be there.
Sheldon: Okay, well, then, he's your plus-one. You don't get to bring anyone else.

Mary Cooper: Lord, thank You. Even though You can do anything, that was mighty impressive.
