I would say most others say something like. "Ummm.. thanks!" and hang up. I don't think they ever really get it. :-)

My favourite is the Jerry Seinfeld response. "Sorry. I am busy right now. Could I have your home phone number and call you back tonight?"

>Good one. But we prefer to waste their time...

>But you say "Usually". What is the answer the REST of the time?

>>My response is "Sorry I don't have a phone". This is usually met with a stunned silence. :-)

>>>With about 10 lines in several businesses I get a LOT of "We want you.." calls from long distance carriers. I tell them they need to speak to "Mr. Dillon". Who of course, doesn't exist. From then on, calls to ANY number for Mr. Dillon get told he's out of the country for 30 days. I think he's permanently relocated to the Sahara Desert now.
