If you're still burning with curiosity on who it was that called you (and if I rec'd a call like that I sure as heck would be), go out and buy a 5 cents-a-minute $5 phone card and call from a pay phone and see who picks up. Have scripts (not like prescriptions but like movie scripts

)in your head as far as trying to ply info from the convo depending on who answers...that is, if you don't just hang up or pull a 'I sorry, I wing da wong numbah?'
