Be sure and do what publishing mogul Rupert Murdoch supposedly does before every long-haul flight.

Take an enema.

Michael Wolff, whose biography of the billionaire, “The Man Who Owns the News” is out now in stores told FishbowlNY.com last week that the Fox News boss always “takes an enema before a long-haul flight.”

Now if that recipe for arriving fresh at your destination doesn’t make you want to make a beeline to the holiday punch bowl, I don’t know what will.

Oh, and make sure that punch is spiked.
