[the Ghost Team] is an ensemble comedy. It's about people who are searching for meaning in their lives, and they end up doing this stupid thing after they're inspired by one another.

I did a pilot for Judd Apatow when I was 20 years old, so 18 years ago. The same year that he did that pilot, he made another pilot called Freaks And Geeks.Judd felt bad for me because I was living in L.A. by myself. Not only did he put me in an episode of Freaks And Geeks, but he was like, "Hey, just come hang out. I'm on set, getting to know everybody." I started hanging with everybody, and they were all either my age or a little younger. Seth and I just got along really well - Jason Segel and I, too - and before you know it, it was a really strong, solid group of friends.

It's really cool to know that you've put something together that isn't for a particular audience. It's so often that a TV show can really only speak to one sect of the population, and this really is something that appeals to a worldwide fan base. People who are into the pursuit of knowledge. Their reaction has meant the world to us.

I got scared away from the whole writing and producing thing, because of how really, truly difficult this was.

To go to L.A. and be on the Addams Family set? It was beautiful production design and an illustrious set. I'm focused on never losing that sense of privilege. I'm still like, "I'm super lucky."

After the writers' strike, I came back with my tail between my legs and apologized to everyone. I had been telling them I was going to leave, and I said, "I'm never going to leave," and that I'd stay with them as long as I can. And I really enjoyed the last two and a half seasons of Numbers more than before.

We [me and Seth Rogen] have always wanted to work together. That was the whole point. We talked about it actively, and then we finally got the opportunity to do that, over and over again. It's kind of a dream come true.
