Last week, we thought Old Spice had gone crazy. Turns out they’ve gone crazy like a fox.

While we were lamenting the possible loss of Isaiah Mustafa, Old Spice and its ad firm Wieden & Kennedy have decided to kick its publicity up a notch by pitting its successful spokesperson against Fabio, who also has had a lot of success as a spokesperson.

Rather than letting its old marketing gimmick go stale, the brand has added a new element – a duel– to keep its marketing fresh and in the news. Kind of brilliant.

In the video below, Mustafa invites commenters to go to all manner of social networks to cast votes for either him or Fabio. The online battle started at noon ET, and you can see other videos at this YouTube site. We’re curious to see how this turns out.
