Three men, one German, one Japanese and a Texan were sitting naked in a sauna. Suddenly there was a beeping sound. The German 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 fellow lifted his palm to his ear. When he finished he explained, "That was my mobile phone. I have a microchip in my hand."
The Texan 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 Texan finally said "Well, will you look at that, I'm getting a fax."
