Snake Snack

Commuters in Copenhagen were recently faced with a giant snake apparently snacking on their bus in this clever guerrilla marketing advertisement for the city zoo. Whether or not they got on the bus or meekly waited for the next, normal-looking vehicle wasn't the point - they couldn't avoid the seeing the enormous boa constrictor and the accompanying ad copy proclaiming the Copenhagen Zoo "The Wildest Place in Town."

The placement of this ad is especially smart because everyone already has to look at buses, for simple reasons of road safety. Ads inside of buses limit their audience to people who use public transportation, but the outsides of the huge vehicles are better than billboard logos because they can't be ignored.
