How was I born

Little boy: Dad, how was I born?
Dad: Well son, your Mom & I got together at Yahoo.
We set up a date via E mail & met in a cyber cafe. 
Your Mom agreed to download data from my PEN DRIVE. ;;) 
So I put it in your Mom's USB PORT 
& just when I was about to transfer
we realised that none of us had installed an ANTIVIRUS or FIREWALL  .
It was too late to hit 'Cancel'
 & nine months later a 'Pop-up' window appeared saying
'You've got 'Male'..
