The quality of any beer is inversely proportional to the coolness factor of any advertising for that beer.That is to say by example if beer company X makes an ad for beer Y and the ad is way super cool, the law states that the quality of beer Y is super crappy. Without mentioning names or dogging any particular brand, let me say that there are several beer companies out there whose advertising is clever and entertaining, occasionally rising to the level of true art. But when it comes to their beer, I'd rather drink an entire pitcher of warm piss.
I leave you to draw your own conclusions about the Rolling Rock ad campaign featured at Moonvertising.com, where you can leave your own message on the moon. I think it takes a day or so for your message to show up. I challenge you to find mine.
