In Vienna we have many germans here (also generally in austria) because since the EU has regulations, that you need to give access to EU-citizens for the same regulations as austrian, they benefit from our educational system. In Austria we don`t have a NC (numerus clausus = grades need to be a certain really good average to be admitted to university) , so we get all the germans to come to us and study. This leads to some interesting stereotypes, specially about "our" humour versus "German" humour.
Austrians can be pretty dark with the humour, and sometimes germans don`t understand that, they sometimes do look kind of puzzled when we talk viennese and use certain language codes , they are not used too. It`s funny, when you make a typical dark humoured viennes joke about sex or death (we do take taboo`s light hearted , poking fun of death as a best friend, and make cynical comments about sex). Germans seem to be offended by these kind of humours and do look at you as if you were taking it very seriously and did something really really bad

I taught a german friend some typical viennese phrases about that and it makes me giggle when he tries to pronounce it
.... (lol)
On the other hand germans seem to be more "precise" which is where they make fun of us austrians.
A german friend of mine used to work as stage assistant, preparing stages for Rock concerts and he wanted about 50 cm between each chair . Of course, for us austrians , this is not meant "literally" , we just estimate with eye sight about half a meter of space. He then told me that he dared to say to the workers "These are not 50cm" and all he got as response was "You must be german, right?"
(lol)
