Howard: I've never done this before, it's kinda fun.
Raj: Yeah, if your mom could see her little Bar Mitzvah boy, she'd have a heart attack.
Bernadette: Good idea. I'll take a picture.

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

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.

Raj: You know, many people believe home births are better because the mother's in a warm, comfortable environment where she can be nurtured by loved ones.
Sheldon: And turn the bedroom floor into an amniotic slip 'n slide.

Amy: Did you hold the baby?
Sheldon: I did.
Amy: And how did it make you feel?
Sheldon: Looking into the blank, innocent eyes of a creature that couldn't begin to comprehend anything I was saying ... basically another day at the office.
