"I can't resist giving you a little story of my all-time favourite brand name: When we were teenagers, everywhere in French canteens, there were glasses supposed to be unbreakable whose brand was engraved underneath. Because of their reputed hardness to break, they were called : Duralex, referring to the well-known Latin proverb "Dura Lex sed Lex" (The Law is Hard but it's the Law). Someone in a glass factory had had the idea of creating a very humorous brand after a Latin proverb. That was so pleasant and witty, and it still is, even many years later."
