Pam: Dwight, am I hot right now?
Dwight K. Schrute: Why would I or anyone else think that you're hot right now? I can't impregnate you, and that's the driving force between male-female attraction.
Pam: What about before? Was I attractive before?
Dwight K. Schrute: Eh. You were at your most attractive when you were 24 with a slight, gradual decline and a steep drop-off when you got pregnant for the first time. Gradual recovery and, uh, well now, obviously, you're at an all-time low.
Pam: Hmm. I think Jim's lying to me about not being attracted to Cathy.
Dwight K. Schrute: You think Jim's lying? [laughs] That's so cute. I know he's lying.
Pam: Five bucks if you can get him to admit it.
Dwight K. Schrute: Done. [Pam goes for a high five] I never touch a pregnant woman.
Pam: Yep, that's the Dwight I need.
