The French existentialist Jean-Paul Sartre was sitting in a cafe when a waitress approached him: "Can I get you something to drink, Monsieur Sartre?"Sartre replied, "Yes, I'd like a cup of coffee with sugar, but no cream".Nodding agreement, the waitress walked off to fill the order and Sartre returned to working. A few minutes later, however, the waitress returned and said, "I'm sorry, Monsieur Sartre, we are all out of cream... how about with no milk?"
