Vikings never wore helmets, Sherlock Holmes never said, "Elementary my dear Watson," and the 100 Years War lasted 116 years. Trivia I learned from ads by age for propmark. The slogan is, "When the advertising is good, it becomes a part of history," and it's hard to argue with the sentiment. (Of course, the ads don't do a very good job of explaining what propmark is.) Via.
