Google Street View just recently launched in Germany. It's possible to opt out of Street View, and in Germany, 244,000 did, asking Google to remove their residences from the service. Not, however, this naked guy in a car trunk.
This image appeared shortly after the service launched, in 20 German cities. Although being posted around the Web as "Naked German Guy in trunk," it's possible it was just a hot day and he got on skimpy shorts or swim trunks.
Later, Google blurred the image out. The dog in the picture probably was happy, as his owner was embarrassing him.
