"My Winnings"

I just got a phone call. The caller said that I have been selected as one of their sweepstakes's winners. "No purchase necessary, but do I have a Visa or MasterCard credit card." I told him I don't. Then he asked, "Do you have a debit card with the Visa or MasterCard logo on it?" I told him no, so he hung up... There go my winnings.
