Three men are sitting naked in the sauna. Suddenly there is a beeping sound. The first man presses his forearm and the beeping stops. The others look at him curiously. “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 man lifts his palm to his ear and starts talking. When he finishes he explains, “That’s my mobile phone. I have a microchip in my hand.”
The third man, feeling a little low-tech, steps out of the sauna. In a few minutes he returns with a piece of toilet paper extending from his ass. The others raise their eyebrows. “I’m getting a fax,” he explains.
