Forget March Madness... here's a bracket I'm taking my time filling out: Playboy is searching for the Best Butt in the world... and we get to help pick the winner.



Head over to Playboy.com/butts, register, and you'll get to survey the 64 models who are competing cheek to cheek.

Make your selections, drag them into the brackets, and the winners, by popular vote on September 14th, move on to the next round. Where we get to vote again. Until the 6 rounds are completed in October and the winner is named.

And here's the best part of the deal: It's not just the chick with the hottest butt that wins... the guy with the most accurate Butt Bracket is going to win a trip to Chicago to sit in on a Playboy photo shoot. (No idea if you'll get to play Oil Boy or not. I'm guessing not.)

Three runners up get trial memberships to Playboy Girls Online Club. Not exactly the same as seeing a hot naked girl live and in person, but then again, you're used to the pixel version by now.

You'll find complete contest rules and prize details... and a whole lotta ass... at Playboy.com/butts
