The folks over at Adult Swim promoted their show by pasting a bunch of these LED-lit versions of the character Err around Boston and nine other cities (the show's website describes Err as one who "may come across as angry and rebellious to some. But everything he says and does is right.")
A couple artists got arrested for installing them. They said they worked for the NY based guerilla agency Interference. I found this interview with Sam Ewen, Interference CEO, from 2001. He talks about other stunts that have gone wrong.
There's a YouTube video of the installation.
And apparently Duracell batteries truly are Trusted Everywhere.
I can only hope that one day a piece of marketing that I've worked on ends up being labeled as a 'suspicious device' and gets blown up by a bomb squad.
