"It was great," Judd Apatow says, "they literally let me edit the magazine. More so than one would expect. I was like, `This is a lot of work!'

If you haven't seen the January issue of Vanity Fair yet – the one with three different covers (Jerry Seinfeld, Chris Rock, Kristen Wiig and Ben Stiller on one, Jim Carrey, Maya Rudolph, Amy Poehler and Will Ferrell  on one, Melissa McCarthy,  Paul Rudd, Leslie Mann and Megan Fox on the other), it's a special all-comedy issue. And special all-comedy guy Apatow  -- taking time off from post-production on This Is 40 and exective-producing Lena Dunham's HBO series, Girls – went at it. Vanity Fair editor Graydon Carter invited Apatow to do whatever he wanted, and Apatow did. There's a story on seminal '60s comic duo (and future filmmakers) Mike Nichols and Elaine May; an interview (by Apatow) with Albert Brooks;  a how Zach Galifianakis writes jokes piece, and a homage to Canadian humor ("Of Moose and Men"), among many other illuminating, laugh-inducing features.

"I got to come up with the ideas for the articles, and I asked a lot of comedy people to write things," Apatow says enthusiastically, on a recent roll-through through Philly. "So people like Lena Dunham and Chris Rock and Albert Brooks and Will Ferrell and a lot of people pitched in. It's pretty great. I think it's actually one of the best things I've ever done."

So, career change ahead? Not likely.

"I'm just a giant fan of journalism and magazines and feature pieces," says the writer/director/producer and Leslie Mann spouse. "It felt oddly comfortable because I'm obsessed with it. For me, it was just thinking, I love Vanity Fair. What if I could pick all the articles, what would I want to read about?"
