This advertisement has been making the rounds among marketing and advertising types this summer. The ending slogan is so obviously ill-advised that one can't help but wonder if it's viral marketing, but perhaps not: Frito Lay's people have been keeping a straight face about the campaign in the trades, and apparently they've redeployed a version of the ad with the embarrassing ending snipped off. Is it the "worst ad bungle in history," as our tipster wonders? Perhaps, but something tells us someone else is going to take it on the chin at least as bad. Pushing nuts is tricky like that.
