Examples that Danish is the most confusing language for English speakers:

In Denmark, when washing machines are done, their displays write, "Slut!", which means "Finished".

When someone enters an elevator, the display changes to "I fart", which means "On the move".

Tourists have difficulty finding a nice WC, because the signs often say "Bad toilet", meaning "Bathroom and toilet".

In lobbies with multiple elevators, one sign may say, "Gods elevator", which means "Freight elevator".

@randahl we liked to take visitors to the room at Den Gamle By in Aarhus playing an old silent movie version of Red Riding Hood just for the visitors reaction to the word ‘slut’ appearing on screen just after a final shot of the heroine.
@FrancescaJ @randahl that's probably very much in line with the original story which was about a young woman losing her virginity.
