What Celeb Could Save the World?

Everyone has the potential to do something good for humanity. Everyone has there own idea what can be good for humanity aside from the general stuff. Could a jazzy idea or witty catch phrase be as powerful as lending millions of dollars to a charity or rescuing someone from a burning building? Not neccesarily, but it could have a similar impact. Can the same be near the equivilent of the opposite, such as ruin people's outlook on life, attitude, morals, etc. I think so, but let's focus on the positive possibilities. When Whitney houston stated in the Barbara Walters interview, "Crack is Wack" during the early nineties, the strength behind her tone and simple yet straight out no nonsense yet casual wording left a healing mark on the culture during that time. People who had their lives' ruined could lighten up their aspect just enough to rhyme out something they didn't need anymore and others could intercept the possibility of future trouble. The power of the influence of one classy(at the time, maybe still) pop star in Whitney did in seconds with clever simplicity what ten public service announcements may not have been able to do in a year. I'd love my readers to talk about a catch phrase from a celebrity that left a positive mark on their lives. If you have to include any kind of profanity, try to use some king of abbreviation or slang please. Thankyou.
