Life in Pieces

CBS

Thats actually based off my real-life situation.

[Jokingly laughs]

Art imitating life.

We will just sit there dying laughing.

Let the line speak for itself.

Its something Justin always wanted with the show.

Hell throw out alternate lines for us and Ill just start dying laughing because theyre all so funny.

He comes up with this amazing material right on the spot.

He and the whole team write such good scripts.

How did this all work out?HUNTER:Ive always wanted to work with Joey.

In the episodes I have seen so far, you havent had any scenes together.

I hope and assume you will eventually?HUNTER:Yes!

Filming those scenes were some of the funniest days.

I will just never forget the things Joey would be pitching to me.

I cannot wait to watch that scene.

Were like best friends.

We dont really fight ever.

I had to pee so often and I was always holding the belly I was very protective of it.

And I also felt insanely bloated those days.

So I guess it felt like actually being pregnant.

I was more hungry than usual too, but maybe thats just because I was hungry.
