Robocall claiming you can enter their sweepstakes by listening to a long list of ads.  They have called my office phone 5 times in the last two months.  Once I happened to be at my desk and answered and that's how I found out about the sweepstakes and ads.  Such as "have you or a loved one ever taken Lipitor and had bad side effects?".  Calling the number gets you the same results, unlike some return robocalls that get you a "fast busy" bad number tone.  I've reported to FTC, maybe they can do something about it.
