In 2006 I presented a paper at a conference in Copenhagen. After the conference was over I visited my wife's family in Austria. While I was there I found this product and couldn't resist buying it as I was dumbfounded that it even existed. It's been sitting in my cabinet ever since until today when I noticed it again.
When I saw it I remembered this old joke I thought of at the time:
It's a communist revolution into the capitalist energy drink market!
Above Che's head it reads "THE REVOLUTION OF ENERGY"
