That's the funny thing. I don't know celebrities anymore. They are thrown at me online and sometimes in TV ads, obviously shown as someone I will quickly recognize and respond to, and I don't know if I am looking at a singer, actor, sports figure, or what. I am greatly amused when some fine looking woman appears and commences to intimate her beauty secrets, obviously relying on the viewers' admiration for her work, and to me she could be another waitress who got a lucky break through an audition for the ad. Okay, so I'm in the geezer cohort, and the ad people don't care. But I'm somewhat alert and curious. So this is also a clue that audiences are so segmented that nearly any A-list celebrity is actually an anonymous stranger to large cohorts of the public. Different genres of music have completely separate stars and audiences, different sports fan bases, different video game or fantasy sports demographics. The idea that any celebrity face rings a bell with more than 30% of the population is a wild fantasy. If Lady Gaga isn't in her stage paraphernalia, I'm not sure I'd even know who she was. In a suit, I might guess she was a CEO of something.
So, for the wanted poster: Big Bird. It would liven up wanted posters.
