A recorded response call claiming I had one a trip to Disney.  Call started out "Can you hear me O.K.?"  Did not respond and the call went on to explain what I had won.  Each time it asked a question, I did not respond and call continued until I did not respond to the question about whether I had a credit card that I would be using on the trip.  When I did not respond after a couple of attempts, it apologized for bothering me and then disconnected.  Heard a lot of warnings about calls trying to get you to respond with "yes" answers to questions so that they can record your response and then cause a lot of long distance calls and minute usage on your cell accounts.
