I'm trying to remember a movie or TV show that PBS ran sometime in the early to mid 1980s. I recall it being called something like "Royal Toilet", but web searching suggests I'm mistaken. This was a Scandinavian film. At the time I thought it was from Sweden, but someone told me it was from Denmark.
As I recall:
The story was mostly set in and around a factory, and was driven by an upcoming visit by the king. Comedy develops from the fact that the king has been suffering from some kind of digestive problem, so there needs to be a toilet available in case he needs it. The factory owners can't imagine sending the king to the communal bathroom that the workers use, so they decide they have to build a special king's toilet to be available on the day. Building this becomes the job of the factory foreman, who is strongly anti-royalist. In the end the king doesn't need the toilet, so the planning was for nothing. The foreman decides that since he built it, he's going to use it. He loudly sings an anti-royalist song while doing so.
