Straight from Behr himself:
When we did the first season [of The 4400], it was a miniseries. And they were, let's say, trying to save money, and they would not put us in a studio. They would not get us offices anywhere, as it turned out. So, well, where the hell are we gonna go? You know, we gotta write six episodes... So they put us in Viacom Productions on Wilshire and Westwood, and so suddenly you have this writing staff with all the corporate suits. And it pissed me off, it really did. And we'd be sitting in the offices, and there was a window on my office, and it was frosted, but there was a little bar of clear glass, and every day I'd look up and there'd be eyes staring at me, looking in, I swear to God, and people would come in and go, "How's it going? How's the scripts going?" I'm going, "It was going great, until you just interrupted me!" So, I got more and more unhappy with the conditions that we were working under, and I came home one day and I talked to my wife and kids and said, "You know, I gotta remember, I'm not them and they're not me. How do I keep remembering that?" And my wife said, "Blue your beard." And my daughter said, "Yes yes yes yes yes!" Of course, I had once met Billy Connolly, the comedian, and he had these long ringlets of hair and this little imperial beard; he was like Wild Bill Hickok, and I said, "Boy, you look awesome, you look great!" And he said, "I used to want to be the most famous comedian on the planet, now I just want to be the coolest dad at The Oakwood School." [Ed note: Oakwood is a Los Angeles private school] And I said, "Wow, that's something I have to remember." And then I decided, hey, Campbell Hall, where my kids go, is even less cool than the Oakwood School, so I could probably be the coolest parent there easily! And at the beginning when I walked in the first time to Jeff and all these people, it was like, "What is going on!?" And it just could not have been better. Now of course they're used to it, and it's a big joke, and it's lost its impact. But my kids like it...
