I heard this one addressed I gues to us telemarketing guys :

Better than some of the owners responses.

"Hello. You are talking to a machine. I am capable of receiving messages. My owners do not need siding, windows, or a hot tub, and their carpets are clean. They give to charity through the office and don't need their picture taken, they have a telephone, dish TV , mobile phone and credit cards. If you're still with me, leave your name and number and they will get back to you."
