Son: Dad where did i come from ?
Dad: Ah, very well, my son,one day yo need to find out anyway ! Mum and Dad got together in a chat room on MSN. Dad set up a date via email with your mum and we met at a cybercafe. We snuck into a secluded room,and then your mother downloaded from dad's memory stick. As soon as dad ws ready for an upload,it was discovered that neither of us had used firewall. Since it was to late to hit the delete button,nine months later the blessed virus appeared.
And that's the story.
