Imagine discovering Bob "Newlywed Game" Eubanks in your trunk. A motorist, unable to find a radio station that's doesn't feature the insistent host of "Instant Powerball, the TV Game Show," realizes it's not the radio at all. He stops and finds Mr. Eubanks in the trunk, then finally agrees to play Power Ball. Doe-Anderson, Louisville, Ky., created the spot for the Kentucky Lottery. Copywriter: Hilary Braun.
