Do you go to that website where it show's all the funny images?
People in the area,obviously find out where the google car is going to be.
They then dress up and you see the images of these guys in scuba diving gear, wearing horse-heads etc
I think I did see that site once, although I'm not sure.
I just googled "google street view funny" and some concerning and creepy stuff showed up. Some of these are going to give me nightmares.
