Duke Law student Andrew Blumberg showed off his "Simpsons" expertise on last night's "Food Network Challenge," and helped cake decorator BethAnn Goldberg earn the $10,000 grand prize.

Andrew, who was introduced on the show as being from Arlington, Texas (no Duke shout out!), was one of four Simpsons Super Fans chosen to compete along with serious cake decorators to craft the ultimate "Simpsons Mystery Cake."

Andrew and BethAnn were assigned a Bart Simpson cake, with instructions to play off the classic Simpsons episode, "Last Tap Dance in Springfield."

Second-year Duke Law student Andrew Blumberg will appear on the "Simpsons Mystery Cakes" episode of "Food Network Challenge" tonight at 8pm.

Blumberg earned a spot as one of the show's four Simpsons Superfans, and was paired with a professional cake designer to create a cake in the likeness of one of the show's main characters: Homer, Marge, Bart, or Lisa Simpson.

Is it the 20th anniversary of "The Simpsons" annual Halloween episode already?

While I've often not found the trio of shorts as funny as a typical episode, they are awfully fun, and this one keeps up the tradition.

It airs tonight at 8.

Playboy is having a lot of fun with their November issue featuring Marge Simpson on the cover.

Done to celebrate "The Simpsons" on its 20th anniversary, the issue is sure to be a collectors edition.

In a press release, Playboy found Hugh Hefner said this:

"Marge Simpson is the quintessential girl next door who stole our hearts 20 years ago and has held them captive ever since.

First we hear that Levi Johnston -- Sarah Palin's daughter baby daddy -- is taking it all off for Playgirl.

Now we hear the next character to go nekked will be Marge Simpson.

It seems the mother of three, who we'll admit keeps herself in pretty good shape, will be featured in a three-page pictorial, complete with an interview for the November issue. (There will still be a 3D Playmate too.)

Not sure how this will go over with feminist Lisa or what the guys at school will say to Bart, but we're pretty sure Homer will be happy.

And we're happy Homer is not going to take it off for Playgirl. Or, far worse, Mr. Burns. Ewww!
