Three people were sitting naked in a sauna. Suddenly there is a beeping sound. The first person presses their forearm and 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 second person lifts their palm to their ear. When she finishes she explains, "that's my mobile phone. I have a microchip in my hand." The third person was feeling decidedly low-tech but not to be out done 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 raise their eyebrows before he says, "Ah, I'm getting a fax."
