Read on the Interwebs today (presented as a true story)
Russia's president Medvedev was visiting a certain Siberian city. About two hours before the presidential cortege was to travel down main street (appropriately titled Oil Workers Street) someone discovered that one of the theatres had a billboard announcing the next production. It was to be a children's story, with the following title being featured quite prominently:
"We wait for you, oh happy gnome!"
According to the onlookers, the billboard was torn down in record time, obliterating all traces of its existence.
