I've seen this movie in polish language for about 10 times and I know it very well, even the dialogs. I've seen it once in german and it wasn't as funny and good as in polish. I think that often the original versions are the best and if the translation isn't really very exact, all films, which base on the dialogues, will be much worse. Of course I know that it's very difficult to translate such films, but people who do this should try harder!
