Costa Rican drivers are getting an eyeful when they pass this billboard for Republica Parrillera Pilsner beer. Looking at the front of the billboard, nothing seems amiss. But when viewed from behind … well, yeah, that does look like a giant penis, doesn't it?
As always with such placements, there's debate over whether this was intentional or a mistake. Proponents of the former say it's brilliant marketing, as drivers who approach the ad from the back are probably fairly likely to check out the front of the ad as they pass—behavior that precious few billboards provoke. Those who think it's a mistake can't fathom the kind of balls it would take to put a giant dick on a billboard.
