Penny: Are you still upset about people finding out you're pregnant?
Bernadette: I'm furious.
Penny: Sure, sure. Uh, did you ever figure out who told?
Bernadette: No. I confronted Barbara Chen, but she claimed she didn't know what I was talking about.
Penny: Hmm. Well, I guess it's just gonna remain a mystery, you know, like whatever happened in that seminar after they dimmed the lights. (laughs)
Bernadette: It had to be Barbara. I've been trying to figure out a way to get back at her. Do you think using her work computer to Google "how to be a prostitute" is over the line?
