Sarcasm is difficult to understand when crossing any language barrier, but yes it is a popular stereotype that the Germans have little sense of humour. I work with several german clients and they don't put up with anything let's put it that way. Just Google it.
Sarcasm is brittle humor turning sour. I think sarcasm betrays a person's own insecurities and doubts; furthermore, it alienates the person from having real connections with others. It's a form of emotionally boxing out other people.
