take it off, Marge

OK, I'd heard about Marge Simpson being on the cover of Playboy. And I'll admit, I don't really get it. What is Playboy getting out of it? Are semi-nude photos of Marge Simpson really going to help their circulation? I wasn't under the impression that she was a female animated character in the league of Jessica Rabbit or Josie and the Pussycats or Wilma or Betty. And is having her on the cover of Playboy going to help the popularity of "The Simpsons"? I mean, yeah, ok, they've always had an adult level to their cartoon, but I guess I'm not getting the benefits of the cross-over, other than that it's kind of amusing.
