This is a boring answering machine message. Leave a message anyway. (Useful to keep people from calling at odd hours to hear your latest exciting message.)

But right now I'm using "This is a boring answering machine message.
Leave a message anyway." because I'm sick of people ringing the phone
at 10am just so they can hear the clever messages I usually have, and
then hanging up without even leaving a "like your message" message....
