"Congratulations Air Miles customer. You have won 260,000 airmiles. Press 1 to accept."
If you push 1, you get put through to the screener who asks:  "Are you over 25?  Do you have a credit card?"
If you answer YES to both, you get onto the next person where they try to sell you a mexican vacation package. You do not actually win anything, so in this sense it is a scam. But after years of getting these calls, I gotten enough information to believe that it's a valid travel offer - but the methods they use to market and call out are extremely questionable.
If I have the time, I like to string them along for as much time as I can waste. It's my game now.
