A thousand years ago man sat down at an inn and ordered a vodka. A waiter came along and forced him to accept a glass of the local wine, telling him that it was much better than vodka, which was not ‘a true drink’. 500 years later another waiter, called Luther, came along and forced him to accept a glass of the local beer, telling him that it was much better than the local wine (he had never heard of vodka). The two waiters then began to argue about which was better, the local wine or the local beer. Rioting started, wars began, rivers of blood poured out. Eventually, all involved grew exhausted and decided to drink coca cola instead.
Meanwhile, the man at the inn is still waiting for his vodka.
