Was macht der Tote auf der Wäscheleine?

The first 20 or so minutes of the movie are pretty funny. Sure, there are some cheesy gags in there, but there is a jovial spirit that makes even these lamer gags ones that make you giggle. However, after that part of the movie ends, the frequency of the gags that work grows slower and slower. Eventually, the laughs totally stop and the remaining portion of the movie is somewhat painful to sit through. I suspect that the major production problems that happened during filming are the chief culprit here, not only explaining the drop in humor but also how some things don't make any sense even for a goofy comedy. (It would also explain how some additional gags seem to have been added in the movie during post-production.) There are laughs here - even a few that would be considered classics of some kind - but nowhere enough. Actually, considering how many visuals of the Dr. Pepper logo that are displayed, maybe it was intended as a commercial instead of an actual movie!
