The War Against Mooninites

BOSTON, Massachusetts (CNN) -- Electronic light boards featuring an adult-cartoon character triggered bomb scares around Boston on Wednesday, spurring authorities to close two bridges and a stretch of the Charles River before determining the devices were harmless.

Turner Broadcasting Co., the parent company of CNN, said the devices contained harmless magnetic lights aimed at promoting the Adult Swim network's late-night cartoon "Aqua Teen Hunger Force." Law enforcement sources said the devices displayed one of the Mooninites, outer-space delinquents who appear frequently on the show, greeting visitors with a raised middle finger.

"While the concern is lessened as a result of the investigation, I'd like to remind citizens to treat any suspicious devices with care and to call 911 if any such device is found," Boston Police Commissioner Ed Davis said.

The devices had been placed as part of an "outdoor marketing campaign" in 10 cities, a Turner Broadcasting statement said.

Fun weekend with ryan, went to a Graffiti show in South Boston. It’s nice to see Boston is getting an underground art scene. We found an Adult Swim LED Ad up on a bridge. So of course I climb up and grab it. It looks like a take on the LED Throwies or Night Writer. Cool stuff though.
