Certain dri doctor commercial

Another major cliche in advertising is commercials that end with the single word "cool" like this insipid entry which ends with not one, but two, "cools. Forgetting that unimaginative device, I can't imagine why a deodorant has to be doctor recommended. Are deodorants dangerous? I also can't conceive why a beautiful woman would go up to a handsome stranger to admit that she was sweating. Is that a provocative opening line? And talk about a leap, why did his telling her that his deodorant was doctor-recommended make her assume he was a doctor? And why did he have to take off his glasses to answer her question? Is there a Clark Kent aspect to this spot I am not getting? Nice looking actors in a really dippy commercial.
