"There are a few times in your life when you have to tell someone to fuck off and mean it." That's what Peter Krivkovich, CEO of the ad agency Cramer-Krasselt, told his client, CareerBuilder.com (and the press), when the client was disappointed in C-K's crop of Super Bowl ads for them last year. And look what happened: this year's CareerBuilder ads (by a different agency) did even worse. To which Krivkovich responded with "a chuckle." Never doubt the brilliance of the "Office Jungle" again! After the jump, this year's kind of revolting ad&mdash not for the weak of heart.[Ad Age/ Jack Flack]
