I've left it up to my dogs to handle telemarketers too. When I saw unavailable on the caller ID I picked up the phone and ran into the living room where all the dogs were crated. That got them all excited and started barking like crazy very loudly as I held out the phone. Whenever they pronounce my name wrong, I say no one by that name lives here. Then there are the times when I answer in spanish "bueno.....bueno?" After saying hello a couple of times they give up and hang up. I'm doomed the day one of them actually speaks spanish.
