The caller ID said Jean Swanson. The caller with a foreign accent said his name was "Jack Dawson." It was another Microsoft Moron trying to tell me that my computer was calling them with a problem.
When I get these calls and have nothing else better to do, I play along. After they tell me there is a problem with my computer and ask me to log on (and press various keys), I tell them my computer is not on and if they'd mind waiting while I fire it up. This can take a minute or two. While that's (supposedly) happening, I ask, "where are you calling from?" If they say Microsoft Windows, I ask how the weather is in Redmond, WA. I like to see how long I can keep them on my hook.
