Modern version of the "Birds & the Bees"
This is much easier to explain than the real facts.
A little boy goes to his father and asks "Daddy, will you tell me
how was I born?" The father debates answering, but finally says:
"Well, I guess one day you will need to find out anyway! Your Mom
and I first got together in a chat room on Yahoo. I set up a date
via e-mail with your Mom and we then met at a cyber-cafe. We sneaked into a
secluded room, where your mother agreed to a download from my hard drive. As soon
as I was ready to upload, we discovered that neither one of us had used a
firewall, and since it was too late to hit the delete button, a blessed
little Pop-Up appeared nine months later and said - You've Got Male!"
