Three men - a German, a Japanese and an American 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 and the Japanese man lifted his palm to his ear. When he finished, he explained, "That was my mobile phone, I have a microchip imbedded in the palm of my hand."
The hillbilly felt decidedly low tech, but he didn't want to be outdone. He stepped out of the sauna and went to the bathroom. When he returned, a piece of toilet paper was hanging from his behind.
"Well, will you look at that," he said, "I'm getting a fax."
