Bernadette: Well, I could ask my dad. Maybe he can get some of his old cop buddies to do a background check on her.
Penny: Would he do that?
Bernadette: Of course. He's a retired cop who plays by his own rules. [on the phone] Hi, Daddy. No, everything's good. I just have a favor to ask. Yeah, so, my friend Raj is marrying this woman that he barely knows, and I wanted to see if you could use your connections to dig up any dirt on her. Uh-huh. Sure. Okay. Love you.
Penny: Is he in?
Bernadette: Absolutely not. He won't do it. It's totally illegal.
Penny: I thought you said he played by his own rules.
Bernadette: He does, but apparently, they're very similar to the actual rules.

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!

Amy: I tried to ask him about it, and he invoked section three, article five of the marriage contract: beeswax, none of your.

Bernadette: Look, I think that's LeBron over there.
Penny: James?
Bernadette: No, LeBron Kershenbaum.

Amy: Hey, did you guys know that Sheldon had a best friend growing up named Tam?
Leonard: Was that the imaginary talking koala?
Amy: No. He's a real person who apparently betrayed him.
Leonard: Yeah, so did the koala.
