here's a plausible candidate for the worst advertisement in the history of our species, and of course advertising is what separates us from the lower animals. you don't see squirrels or viruses trying to get you to buy stuff with a steaming pile of hooha. obviously, the whole thing is neuro: this thing triggers the advertising region of your brain, which is just at the crown of the head. and of course, any very pervasive feature of our species has been selected for by evolution, and really bad ads are evolution's crowning achievement, the only reason that we have, sadly, survived and adapted and become so amazingly incredible.
