The ad campaign for the Gillette Mach 3 razor is pretty hilarious, turning an elevator into a something that requires a much-needed shave. The elevator's walls have been covered in hair to try and promote the razor and its insane manscaping abilities.
I think this is one of the more clever ad campaigns I've ever seen. Not only does it really attract the attention of all the elevator riders, but it's interactive and fun, probably getting the men thinking that they should start growing beards, just so they could shave them off with the Gillette Mach 3 razor.
