You are on your way to work or maybe school, you drive along the road and suddenly you see a giant bus driving towards you. Don't worry, it's only an illusionary billboard sticker. Everyone would be frightened by this huge ad that an insurance company created to rise attention about their service.
It's an long-used slogan of the 'Centraal Beheer' insurance company, located in the town of Apeldoorn, The Netherlands. They also do 'short film' type of commercials. (The slogan translates in something like 'just call to Apeldoorn'.)
