Telemarketing scam call, where a computer controlled series of recordings is used to ask questions and then try to imitate a real person by anticipating your verbal responses and playing a recorded response.  "Leslie" (I'm sure that's the computer's real name) informed me that I'd just won an all-expense paid trip, complete with rental car and meals, because I'd stayed in one of her company's resorts in the past.  Riiiiight.
