The girlfriend and I have come back from our well-earned (at least in her case) week in Vienna, where we touched base with friends and family.
Like every time I visit my old haunts at the Vienna Technical University, I also participated in the old Viennese tradition of urine-imbibing. Dating back to the 18th century, where doctors used to diagnose diabetes in their patients by tasting their urine, this tradition is still upheld by the members of the academia in Vienna. Customarily the urine (either your own, or that from a good friend) is drunk out of Erlenmeyer-flasks, like on the picture on the left.
Since it is an acquired taste, teenagers often mix their urine with beer or wine, but in my opinion that rather cheapens the whole experience.
