We were in Darmstadt a few years ago and we went into a bar. A gentleman went to the toilet and one of our party joked that he might be away for a crap ( Don't ask, it must have been an in joke at the time) When he returned he said to us No, it is Kraut you say, Kraut! We looked at each other puzzled and he left. Then it dawned on us that he had overheard us and misheard the meaning. It was all very confusing and a little embarrassing. The point is right enough he certainly wasn't bothered about being called a Kraut.
