That's part of the comedy, too, is we do have jokes throughout of hanging a lantern on the absurdity of the world. Like, when BoJack's flying over the neighborhood, you see some houses have swimming pools in the backyard, and what does that mean? Why would there be a swimming pool underwater? But we thought it was funny.

It was fun figuring out the science of the world as much as we wanted to figure out, and then playing fast and loose in other places. Which we do with our show in general. One of the things we love about the BoJack Horseman show is that we can always fall back on, "It's a ridiculous cartoon." And it is! It's a serious, relationship-based grounded character tragedy, but it is also a ridiculous cartoon.

Jessica Biel is a really interesting case. She actually called us after the table read and said, "You guys should go meaner." She pitched us, and said, "Look, I know there are a lot of things to make fun of me about. I don't want people to think you're pulling punches. Please, dive in." We asked, "Could we tell a joke about your friend and mentor Stephen Collins?" And she said, "Well maybe not so much in that area. As long as the jokes were about me, I'm game for everything."

I am wary of repeating myself too much. In this age of Netflix, as a Netflix show, if you want to go back and watch a season 1 episode, you can do that easily. I'm not interested in repeating the same story beats over and over and over again. But part of the truth of BoJack story is about how much he repeats himself and these patterns that are difficult to get out of. I'm trying not to be evasive about that. I'm not using that as an excuse. I think that's convenient to fall back on as a TV writer: "Oh, it's a show about stagnation."

We often ask, "Do we have enough humans?" Because it's always fun to come up with an animal in show, but it begins to feel like overkill.

This is why Jessica Biel is a successful actress: because, despite the punchlines, you know how to tell a joke.

In a certain way, sometimes it does feel like we say goodbye to a character, and we don't want to bring them back unless we have a good reason. We left the door open if we wanted to use him more. I always think it's better to leave the audience wanting more.
