Jake and Mary have an agreement that anytime they want to make love, they will call it a "PHONE CALL".
One day Jake sends his son to tell his mother that he wants to make a phone call and Mary replies; tell your father, there is no network..
Jake: tell your mother that if there is no network at home, then I'll go to a public phone..
Mary: tell your father that if he dares go to a public phone, then I'll open a call center at home.
