While in the restroom, I learned about the other meaning of the word "Belgium". On the wall in front of my was a small poster with Marvin the robot from The Hitchhiker's Guide to the Galaxy stating that throughout the rest of the galaxy, Belgium is the most unspeakably rude word there is.
At the time of my visit to the restrooms, I was in a belgian pub, in a belgian city (for short: I was in Belgium). Quite amusing that they choose to promote the movie in that particular way.
