Great to see that some old posts recommending this game didn't get lost in cyberspace. Small item of note: 'Schrille stille' is indeed out of print but is still easily obtainable in Europe. In fact, shrink-wrapped copies were available at Essen for the astounding price of 9 euro. AllGames4You still carries the game at less than 10 euro.
The game itself is not ultra-great due to it being a bit too chaotic but the goober really makes this game a lot of fun for gamers and non-gamers alike.
