The family's dream vacation is interrupted when Hurricane Irene blows through the Hamptons. Faced with a big decision, the family remembers the seriousness of Katrina and reckons they can ride out Irene. Boarding up the house, stocking up on beer ... er ... hurricane supplies ... and hunkering down has never been so much fun. And, in the aftermath of what was described as a "historic hurricane," the family turns their lush backyard into their very own mud hole. When the neighbors arrive, it's only a matter of mud before these Northern neighbors are converted to the Clampets' Southern ways.
