Boy: daddy? how did i come into this world??
dad: listen carefully..
mom & dad met each other in a cyber cafe...
in the restrooms of that cyber cafe,
dad connected to mom a big usb.
mom at that time made some downloads from dad's memory stick...
when dad finished uploading we discovered we did not use firewall...
since it was too late to cancel or delete,
nine months later we ended up w/ a virus...
...hahahah!
