To the operators who are so upset about this: get over it. You get paid no matter what you say… why do you care? You should be happy the federal government pays the phone company to keep you employed (that’s the real travesty, that tax dollars pay for this service.)
And to anyone who says this is illegal: It’s only illegal to make prank calls with the intent to annoy or harass. If you’re doing this to your own answering machine, you’re friend’s answering machine who thinks its funny, etc, you’re in the clear. Or if you’re using it to call in sick to school you’re in the clear. So have fun!
