Last month Mullen unveiled the “#worldstoughestjob” Mother’s Day campaign for client card company American Greetings that was sort of a Candid Camera meets Craigslist approach. The agency posted an online help wanted listing for a “director of operations” position and then recorded the responses of candidates as they listened to the requirements during an online interview. Unbeknownst to the candidates, the listing was for the job of Mom and included requirements such as standing up most the time, no time to sleep and no vacations. Oh, and no salary either. Lunch break? Sometimes, maybe. The upshot? The video became a huge viral hit -- to date it has been seen more than 20.6 million times. Now the agency and client have teamed up to try to capture lightning in a bottle one more time with a Father’s Day sequel called “Dad Casting.” The structure of the video is a “casting call” for the role of dad. The actors don’t know it has anything to do with American Greetings. According to the agency the creative premise is that “fatherhood is full of unscripted moments.” The goal is to generate appreciation for dads and their parenting, a job that, like the role of moms, is tougher than it looks. Consumers can participate in the conversation by tweeting unscripted dad moments and explaining why the dad in their life deserves a standing ovation. Every #worldstoughestjob hashtagged card, tweet and post about dad is tallied up by a “Dadmiration Tracker” and displayed on a blog landing page. The “Dad Casting” video can be seen here.
