Here’s a way for making prank phone calls. It lets you specify the caller ID and telephone number that will appear on the receiver’s telephone and give the message in a computer-animated voice.
I immediately thought of this practical joke. On the day they hand out the Nobel Prize for literature, call 100 novelists, indicate on the caller ID “Nobel Prize Committee–Stockholm) and have the computer recite the message, “You have NOT won the Nobel Prize for Literature this year.”
