An American, a Japanese, and a Nigerian were sitting naked in the sauna. Suddenly there is a beeping sound. The American presses his forearm and the beeping stops. The others look at him questioningly. "That's my pager," he says. "I have a microchip under the skin of my arm." A few minutes later a phone rings. The Japanese lifts his palm to his ear. When he finishes he explains, "That's my mobile phone. I have a microchip in my hand." The Nigerian, feeling decidedly low-tech but not to be outdone,decided he had to do something just as impressive. He steps Out of the sauna and goes to the toilet. He returns with a piece of Toilet paper hanging from his butt. The others raised their eyebrows and said, "Wow! What's that?" "I'm getting a Fax," he explains.
