I found this on AdFreak and oh man, it made me smile.
Apparently this bus advertisement was broken into and destroyed just two days after being installed in Chicago. Originally the ad was filled with different types of junk food - the snacks were supposed to be taken away slowly after a four-week period, to reveal the tagline, "Too much good stuff." However, local hungry people greatly shortened that timeline and destroyed the ad almost immediately. Ironically, they didn't like the Doritos at all - guess we should all keep brainstorming - even though the One Show deadline has long since passed.
