Some Joke… computer related

CHILD: Dad, where did I come from?
DAD: Okay, we had to have this conversation some day!.. Listen… Dad and mom met in a chat room on the net. I set up a meeting with your mom and we landed in the bathroom at the CyberCaf?
Then, mom did some downloads from dads memory stick
and when dad was ready to upload, we discovered that there was no firewall.
Seeing that it was a bit too late to cancel, I just carried on doing the upload.
Nine months later, the damn virus appeared!
CHILD: Huh?
