I'm not a German speaker (well, I do understand a good bit but my grammar is almost nonexistant) OR a native English speaker, so I totally see your point, TashSunrider. It seems like if they're going to include German, they should take their time and make sure it's correct, assuming that they weren't going for a joke that we're not seeing.
Hey, maybe it'll even get explained in a later chapter, I'm kinda guessing there's going to be more to the Courthouse, and they strongly hinted at us seeing more of the Voodoo Lady's chest of unmentionables, or whatever, so maybe Guybrush will be back to Flotsam Island.
I'm kinda hoping that there's something behind their poor use of German, just so I won't be disappointed in them
