How did I come into this world

A Kid asks:"Daddy? How did I come into this world?"

The Daddy Answered:"Well, my child,
some day I'll have to tell you any way,"
The Kid asked again: "So why not today?"
The Dad Respond: "Please, listen carefully:
Mom and Dad met each other in a cyber café. In the
restrooms of that cyber café, dad connected to mom.
Mom at that time made some downloads from dad's memory
stick. When dad finished uploading we discovered we
used no firewall. Since it was too late to cancel or
delete, nine months later we ended up with a virus."
