Gillette has unveiled a new ad campaign for its Proglide series that centers around two divers shaving underwater in the Bahamas in baited shark scenario. The ad uses the old “sharks can smell a drop of blood from a quarter of a mile away” bit and portrays the sharks as becoming seemingly aggressive after one of the divers after apparently nicks himself shaving with an inferior disposable razor.

So, the next time you’re doing a shark dive and decide that you need a shave, remember to use you Gillette Proglide. If not, quick edits and ominous music are sure to follow.
