How did i appear in this world?

Son: How did I come to the world?
Father (is surfing): I'll explain it to you later.
Son: Why don't you tell me right now?
Father (is thinking of a sorrow and sighing): All right! You listen to me very carefully...

"When your mom and your pa visited Internet together in the bedroom, your pa connected with your mom. Your pa uploaded some data from his "memory stick" to your mom. After your mom downloaded all stuff, she screamed that she had not installed any "Anti Virus". And your pa had not installed any "Firewall" either. Both of us tried to delete the file and format the "hard disk" but found it's too late."

"Then, you appeared in the world after nine months."
