Such a marvelous idiom: Bummelzug, “boomelzoog,” the slow train that stops at every last station along the way. Here a pitiful little provincial station with terrible facilities posts a sign, “Please keep clean.” The caption then reads: “Important rule in the battle against epidemic diseases (salmonella, typhus, dysentery): Thorough hand-washing after every visit to the restroom!” Which prompts the rhyme (in German):

Whoever wants to comply with this rule,
He’ll never be traveling on slow trains!

Draw appropriate hygienic conclusions.
(Nebelspalter, Zurich, 1966)
