I actually answered because I was anticipating a long-distance call, but the guy started saying something strange about a package he'd sent me, so I hung up immediately.
Called my cell saying I had won a vacation contest I had entered. Said that I had been entered by my father, whose name is on my phone account. I said I thought it was a scam and that I wouldn't provide any personal info. He said they needed no info from me, and that I had to come pick up the prize at their main office in my home state. He couldn't give me the address though, and said he would call back tomorrow with an address...... sketchy as hell.
