The French philosopher Jules Henri Poincaré was relaxing in a cafe when he a waitress approached him and asked, "Can I get you something, Monsieur Poincaré?"
Poincaré replied, "Yes, I'd like a cup of coffee with sugar, but no cream".
The waitress returned after a few minutes and said, "I'm sorry, Monsieur Poincaré, we are all out of cream - how about with no milk?"
