A modern version of the stork...

Little boy goes to his father and asks "Daddy, how was I born?"

The father answers: "Well, son, I guess one day you will need to find out anyway! Your Mom and I first got together in a chat room on Yahoo. Then I set up a date via e-mail with your Mom and we 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, nine months later a blessed little Pop-Up appeared and said:

"You've Got Male!"

With thanks to Black Feline for this one!
