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 cell 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?"
