I just saw the creepiest ad in my life. It is a TV ad for One Laptop Per Child in which John Lennon is brought from the dead to endorse this program. First you hear a voice similar to Lennon's talking about the idea behind One Laptop Per Child and then we see old Lennon footage talking to camera. what's worse the lip synching is not even that good.
It is a strange concept for a commercial. Maybe it will work since it will certainly get people talking. But still, the fake Lennon voice is really, really creepy.
