My friends and I have fun with these scam artists. We lead them on for days and weeks, then they finally get mad and "go away". We've even talked on the phone to them. Background noise sounds like a factory somewhere.

My buddy selling a BMW told the "buyer" that his favorite bootleg KISS live concert tape was stuck in the deck, and it would take a few days for the local shop to get it out without damaging it first.

I told one guy that my volvo 240 station wagon was being professionally cleaned up, and that I was a volunteer for transporting sick monkeys from one zoo to another, but that you can kinda get used to the smell. That got a funny reaction.

Have fun with them. It's cheap and creative entertainment. Give cell phone number only of course.
