If they had they probably would've avoided the painful sting of irony. Right around the time Clapton's commercial was released, he decided to come clean... literally. Clapton fessed up that he was currently seeking treatment at a detox facility... for alcoholism.
Upon finding out that the centerpiece to their multimillion dollar ad campaign was in rehab trying to liberate himself of imaginary bugs, Anheuser-Busch promptly terminated the contract. They wanted an image of carefree people happily drinking in a smoky bar, damn it! Not of some guy responsibly seeking help from professionals when he realizes he has a problem!
These days, Anheuser-Busch has learned their lesson, stopped pretending beer is part of some kind of imaginary rock star lifestyle and now claims Michelob will turn you into a top athlete instead.
