J.D.: It's a front. She's miserable. So far the highlight of the night's been putting the possum to sleep and that's not a euphemism.
Elliot: J.D., seeing a young doctor do his job is an amazing turn-on for a girl. My dad's a doctor, and I remember how excited I was the first time I saw him work at the hospital. I mean, I didn't want to sleep with him, but there were definitely some complicated feelings. But that's totally normal for an 11-year-old, right?

Kid: Way to go, daddy!
Mr. Phillips: 'S my biggest fan!
Elliot: Heh. Umm... Do you smoke cigarettes?
Mr. Phillips: No way.
