Foreign Phrase: Jetzt ist Matratzen horch alarm!

In English we’re prone to taunting someone playfully before going to bed by warning them: “Don’t let the bedbugs bite!”. This German phrase is used similarly. Literally, it means “The mattress is on high alert!”, and you can use it as a way to say Good Night in German.
So sleep tight laddies, and remember: “Jetzt ist Matratzen horch alarm!”
