Next to Normal/Funny

"Better Than Before" is full of these. Such as;

Diana: And who's this little chubby girl?
Dan: That's Natalie!
Natalie: This sucks.

Natalie: Here's the damage to the Honda when you showed me how to park it.
Diana: Did we crush somebody's cat beneath the tire?
Natalie: Yes, ours.

Diana: [To Natalie] Your life has kinda sucked, I think.
Natalie: You've got it! Yay, hooray!

Doctor Madden's rock star moments just before My Psychopharmacologist and I.
And Diana in "Seconds and Years":

Dr Madden: Do you still feel your head is filled with concrete?
Diana: No...and you're not a scary rock star anymore!
Dr Madden: Ok...great.

Diana in "Just Another Day":

So my son's a little shit, my husband's boring/And my daughter, though a genius, is a freak...

- Additionally, her blithe declaration to Natalie:

Diana: Honey, you need to slow down, take some time for yourself. I'm going to have sex with your father.
Natalie: Great, thanks, I'm...so glad I know that.

Feeling Electric in the off-Broadway run, which takes Doctor Madden's brief rock star moments and makes a whole song out of it.
"I mean, Portland?"
