Bernadette: Hey, what you got there?
Howard: Oh. [stammers] Just tossing out this old helmet I don't need. I thought you were at the park.
Bernadette: We were. The kids got sleepy.
Howard: Great story. I need to make a phone call.
Bernadette: Howard, why do you look all guilty? Like when I catch you deleting your browser history?

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!

Bernadette: Why do you want to ride that stupid thing anyway?
Howard: I don't know. Maybe I just miss the freedom I had as a younger man.
Bernadette: What freedom? You lived with your mother. You had a curfew.

Howard: This is a twist. Usually you're the one getting called into H.R.
Raj: Yeah, now it's Amy. Who knew you were married to such a bad girl.
Sheldon: I suppose the signs were always there. I mean, she did recently go to that rave at the mall.
Amy: It was a Spencer's Gifts.
Sheldon: There was music and a strobe light. If that isn't a rave, then I don't know what one is.
Leonard: You don't know what one is.

Amy: Guys, come on, I think I'm in trouble.
Howard: It's no big deal. I used to get called into H.R. all the time. Ms. Davis is great. Pro tip: if you find strong women sexy, do not say it out loud.
