This Is Just So Wrong
So of course, it's being used in outdoor advertising here in New York. Innocent pedestrians (well, innocent by New York standards) are assaulted by a bodiless voice murmuring "Who's that? Who's there?" It is then followed by: "It's not your imagination!"
I have two reactions to this: 1) Shades of Philip K. Dick, and 2) How stupid do you have to be to put additional voices inside the heads of already stressed-out NY pedestrians?
Give props to my fellow New Yorkers, though. The offending speakers were stolen twice in one day.
Gawker's "Schizophrenia Is The New Ad Gimmick" got it right.
