A boy goes to his father and asks him: "Daddy, how was I born?"
"Ah, very well," His dad sighed. "One day you'll find out anyway. How shall I put it in a way your generation will understand...
Well," he said "mom and dad got together in a chat room. Dad set up a date via e-mail with your Mom and we met at a cyber café.
We snuck into a secluded room, and then your mother downloaded from your dad's memory stick.
As soon as dad was ready for an upload, it was discovered that neither one of us had used a firewall.
Since it was too late to hit the delete button, nine months later the blessed virus appeared.
And that's the story!"
