An American, a Japanese man and and Irishman.
Suddenly there's a beeping noise. The American touches his arm and says "it's my pager, I have a microchip under my skin."
Then there's a ringing sound. The Japanese man lifts his palm to his ear and says "it's my phone. I have a microchip in my palm."
The Irishman, feeling very low tech, goes off to the toilet and returns with a length of toilet paper hanging from his arse.
"Oh Jaysus would ye look at that, I'm getting a fax."
