In the season 1 episode, "Vanity, Thy Name is Human," Beth refers to the high school where she and Kevin attended as Staten High. However, in this episode, Kevin's high school yearbook says Jefferson High.
When Joan enters the hospital room to see Judith, there is someone in-shot at the back of the room, but when Joan leaves, the person is gone.
Just after Adam leaves when Judith says her parents are "shrinks", several students (most notably a blond girl with a white binder) walks by them. The next shot shows the same kids walking past her again.
Will: Just once I'd like someone to do the right thing. Once!
Det. Carlisle: You're still a dreamer. It's cute.
Grace: (about Joan) If she had an off switch, I'd use it...
Luke: High school house party. A primordial soup of hormonally charged organisms just longing for a lightning bolt and a little innocent mitosis.
Will: What happened to the cheery, optimistic Joan?
Joan: I found no future in optimism.
Joan: I didn't really want you to shake your booty.
Adam: That would've been ugly.
Grace: ABBA… and those little meatballs. No wonder Sweden's filled with drugs.
Joan: How do you deal with your dad being all into God?
Grace: Sometimes I hide his yarmulke and watch him freak…
Grace: So now I have to get to know another person now...
Grace: Olatunji. African drums.
Luke: Pretentious attempt to co-opt another culture to hide your middle-class roots.
Grace: You're going to be bleeding soon.
Joan: Why can't you understand that you are screwing up my life? I just want to be like everyone else!
Goth Kid God: I really have to give you the snowflake speech?

Old Lady God: being hit by a car
This appears to be the second, albeit less direct, reference to the TV series The West Wing in two weeks. In that series, in the episode 18th & Potomac, the character Kathryn Joosten played, Mrs. Landingham, was hit by a car. Here her character gets hit by a car too. Barbara Hall must be a fan.
