advertise on your forehead

formerly a daring fashion move reserved for (bone)heads and their Union Jack Flags - Now even the posh Guardian wants you to label your forehead.

Of course this is the Guardians answer to the press release Students cash in on 'human billboards' plan they published earlier. The concept isn't entirely foreign - remember the lad who said SponsorMyMelon.com and rented out his bald head back in the fall of 2001?
The agency getting all the media attention right now is aptly named Cunning Stunts. They offer students up to £88.20 a week to wear a corporate logo on their head for a minimum of three hours each day. So far laddish magazines like FHM and the channel CNX have signed up for the interesting media plan...
but what happens if the forehead labeled doesn't go with your brand? Say an avid pepsi drinker wears a Coke logo, and still drinks pepsi in public...
Or how about the situation where the owner of the forehead dislikes the brand he is advertising and when asked only spreads bad rep.
and when will this stretch to include real tattoos as advertising space? ;-)
Nice idea but no hand rolled cuban smoking material...
