I'm pretty surprised by how often I win those things. If I'm driving and a contest of any sort comes up, I'll call the number immediately and repeatedly for a few minutes, just hanging up and pressing redial. Anecdotally, I seem to win whatever prize in about 1% of those that I dial in for. I've found that I sometimes don't even receive the prize, and occasionally don't even know what the prize or radio station are when I'm calling in as it's reflexive at this point.
