The show with the mouse: Costume Party
"Die Sendung mit der Maus (The show with the mouse) is a children's series on German television...

It contains mainly short featurettes that uncover some of the things that go on in the world, whether in technology and industry or something as mundane as how the postal service works. Most of these are interesting for adults as well, making the show suitable for the whole family. Each show takes 30 minutes.

Every show begins with a brief summary of the featurettes, commented in German, which is then repeated, this time commented in a foreign language, followed by a comment like "Das war Schwedisch." ("This was Swedish.")..."
