An American, a Japanese and an Irishman were sitting naked in a sauna. Suddenly there was a beeping sound. The American 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 fella lifted his palm to his ear. When he finished he explained, "That was my mobile phone. I have a microchip in my hand." The Irishman felt decidedly low tech, but 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 Irishman finally said, "Well, will you look at that. I'm getting a fax."
