Unlike the brand's Super Bowl ad for its "all natural" burger, which nearly showed "model Charlotte McKinney in her birthday suit" (as Ad Nut's friends at Campaign US put it), the only things going au naturel in this ad are fungi and cheeses.
Ad Nut prefers this more clever, less direct approach, but remains disturbed that Americans are apparently so aroused by big, juicy burgers.
Incidentally, Ad Nut is certain that shooting pictures of food items lit and cropped to look like body parts is by no means original, but Ad Nut cannot provide a link because it's not wise to continue Googling phrases like "naked food pictures" or "sexy vegetables" here in the office.
