This post is verboten to German speakers. The picture is the more or less original sign of the 1950's Blinkenlights joke I have in the basement. It's not German at all of course, it's colloquial English phrases substituted with made-up German words. Carefully made up so they use English roots, so that any English speaker understands them immediately (snap the spring works = schnappen der Springenwerk, not to be operated by dimwits = nicht fur Gewerken bei Dummkopfen, etc...).
