Stuart: Bernadette still going stir-crazy?
Howard: Oh, a little. Two months of bed rest, it's kind of rough.
Raj: Really? That sounds great. How do I get that?
Leonard: You'd either have to break your hip or let Howard knock you up.
Penny: Now, either way, you'll get flowers the next morning.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

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

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Penny: Look, I know this is your wedding, and you can do whatever you want, but if you think anyone but me is gonna be your maid of honor, then you're an idiot because you are my best friend.
Howard: Too late, Bernade-
Amy: (pushes Howard out of the way, rushes to hug Penny) Bestie!

Sheldon: Did Bernadette even try to send us a sewing kit?
Amy: She did. Amazon, standard shipping, not even Prime.
Sheldon: (gasps) We could've done that ourselves.
Amy: (chuckles) That's what she said.

Amy: Okay, what's the next test?
Sheldon: Loyalty. We need to choose someone who has our backs, someone who will keep our secrets even from each other.
Amy: Well, I don't have any secrets from you. Do you have secrets from me?
Sheldon: Yes. Oh, that has been weighing on me for years.
