You are in big trouble now

Hello! I'm on a four state killing spree! WATTA YA WANT?
Hi, I'm not home because I've gone on a BLOODY RAMPAGE! When I get home, and CLEAN OFF THE BLOOD, I'll be sure to give you a call. If I haven't ALREADY COME OVER, that is. (Coughing loony laughter.)
(Italian Mafia-style voice:) I can't come to the phone right now. Me and Guido are trying to stuff a body in the trunk. I think we're going to have to size it a little... (Aside:) HEY GUIDO! GET THE CHAINSAW! Anyways, leave your name and a message. If I like it, you'll hear from me. If not, you'll hear from Guido! (Laughter.)

Leave a message or I'll send 30,000 volts through your phone. I am an electrical engineer. I can do that.
This is Dan Cassidy's answering machine. Please leave your name and number, and after I've doctored the tape, your message will implicate you in a federal crime and be brought to the attention of the FBI.
You have reached the CPX-2000 Voice Blackmail System. Your voice patterns are now being digitally encoded and stored for later use. Once this is done, our computers will be able to use the sound of YOUR voice for literally thousands of illegal and immoral purposes. There is no charge for this initial consultation. However our staff of professional extortionists will contact you in the near future to further explain the benefits of our service, and to arrange for your schedule of payment. Remember to speak clearly at the sound of the tone. Thank you.

Please leave a message. However, you have the right to remain silent. Everything you say will be recorded and will be used by us.
Shhh! Don't talk, just listen! Meet me at the corner of Broad and Main and bring the girl. (CLICK)

After the tone, leave your name, number, and tell where you left the money. I'll get back to you as soon as it's safe for you to come out of hiding.

My time is billed at $125 per hour. Please begin your message with your MasterCard or Visa number, card type, and date of expiration. I'll get back to you pending credit approval.

Hi, this is Jim. Welcome to my Fun Phone Line, where you can talk to my answering machine for only $0.95 per minute! Please leave your credit card number at the tone...
