Personally, I think I would have to tell the story of enjoying the NOW... to appreciate the moment you have at this second, because that is all that we have at any given time... and that our power is with the choices that we make RIGHT NOW...
I think it would just be a 30 second fart joke. At the end of the day those are the commercials people remember. Besides in that short amount of time I'd rather make you laugh than anything else. In today's climate a good laugh is priceless
Dove actually made a very effective "message" commercial for the last Super Bowl (or was it the one before that). Laughs are easy and reliable, and they are probably the way I would go too in the hopes that conformity might overcome personal incompetence. But a well made spot that speaks to people on an emotional level that can be more compelling than comedy.
