Like water on a goose - Swedish

Just thought of one that takes a bit of explanation. In Swedish, much like German, words are joined to create longer words. Such as smörgåsbord(sandwich table). The smurfs in Swedish are therefore called gammelsmurfen (old smurf), "anything"smurfen. Because of this, people jokingly say “intressesmurfen antecknar” ( interest smurf is taking notes) to indicate that they don’t care about what somebody is saying
