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.

[Numbers] made me feel like a real person instead of a guy who shows up for two days on a movie, does some funny stuff, and then doesn't see anybody until the premiere.

It was just like, "What am I going to do today, in L.A., as an actor? Well, I guess I could go to Seth's [Rogen] apartment and smoke weed and hang out." And that's all we'd do. We'd smoke weed, hang out, play video games, and talk.

Halfway through Numbers, I got really jaded, and I had these unrealistic expectations about what Numbers could be. I thought it should be Emmy-nominated. I was in my mid-20s, so I was kind of shortsighted and silly.

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

At that time in my career, everything ended up moving so fast, honestly. Within the first five years of my career, I think I did two TV series and four big movies, and I've never been that hot again in my career.

[Gigi Does It show] flew so drastically under the radar. I kind of hold it in my back pocket as this thing that I got the opportunity to do that no one really knows I did and that I'm really proud of.
