Image: An April fool in Denmark, regarding Copenhagen's new subway. It looks as if one of its cars had an accident, and had broken through and surfaced on the square in front of the town hall. In reality, it was a retired subway car from the subway of Stockholm cut obliquely, with the front end placed onto the tiling and loose tiles scattered around it. Note the sign "Gevalia", the coffee is known for its advertising featuring vehicles popping up: be ready for unexpected guests.
