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.
