Clone of "scratch me if you can". “Scratching” is a form of vandalism apparently derived from sprayed graffiti, in which tags are scratched into windows (usually), mostly of public transportation vehicles and street furniture. This phenomenon has apparently begun in the early 1990s. In Germany, scratching is especially prevalent in Berlin, Munich and the whole Ruhr-Area where literally no public transportation train car is without scratched windows, despite traffic companies spending 12 million € on repairing and exchanging scratched windows in 2005 alone. During the 2006 FIFA World Cup, numerous visitors complained about the scratched windows." -wikipedia done with a much finer needle :D
