Prue: Stop. You're obsessing.
Piper: Well, it runs in the family.
Prue: I don't obsess, I think...intensely...anyway. I can't really help it. I mean, we've seen so many bizarre things, why not a man in a painting?
Dan: Okay, I'll tell you what I can do. I'll check the code violations. See how serious they really are. If you help me with a promise I made to Jenny.
Piper: Deal. Uh..wait, what's the promise?
Dan: She needs help with a paper. It's for her bio class, you know, something about the human reproductive system.
Piper: Oh, ha. You mean sex.
Dan: It's just way too awkward for me to talk to my niece about.
Piper: Yeah, sure. Don't worry, I have plenty of experience.
Dan: Really...with the sex?'
Piper: No..I mean, uh...talking about it.
(Prue is showing Piper Phoebe's drawing of the human reproductive system)
Prue: Okay, you wanna explain this?
Phoebe: Okay, well that's Piper. (points to the egg)
Prue: Oh, I see...
Phoebe: And that's Dan. (points to the sperm)
