THREE MEN--ONE GERMAN, ONE JAPANESE AND A HILLBILLY--WERE SITTING NAKED IN A SAUNA. SUDDENLY THERE WAS A BEEPING SOUND.THE GERMAN PRESSED HIS FOREARM AND THE BEEP STOPPED. THE OTHERS LOOKED AT HIM QUESTIONINGLY. "THAT WAS MY PAGER," HE SAID. "I HAVE A MICROCHIP UNDER THE SKIN OF MY ARM." A FEW MINUTES LATER, A PHONE RANG. THE JAPANESE FELLOW LIFTED HIS PALM TO HIS EAR. WHEN HE FINISHED, HE EXPLAINED, "THAT WAS MY MOBILE PHONE. I HAVE A MICROCHIP IN MY HAND." THE HILLBILLY FELT DECIDEDLY LOW TECH. NOT TO BE OUTDONE, HE DECIDED HE HAD TO DO SOMETHING JUST AS IMPRESSIVE. HE STEPPED OUT OF THE SAUNA AND WENT TO THE BATHROOM. HE RETURNED WITH A PIECE OF TOILET PAPER HANGING FROM HIS BEHIND. THE OTHERS RAISED THEIR EYEBROWS AND STARED AT HIM. THE HILLBILLY FINALLY SAID, "WELL, WILL YOU LOOK AT THAT. I'M GETTING A FAX."
