Our script supervisor is Danica Johnson. The graphics team is Thought Bubble, and the show is written by my high school history teacher Raoul Meyer and myself. Last week's Phrase of the Week was also good advice. Quit smoking! If you want to suggest future Phrases of the Week or guests at this week's, you can do so in comments, where you can also ask questions about today's video that will be answered by our team of historians. If you liked today's video, please click the thumbs up button. You can also follow us on Twitter at The Crash Course, or on Facebook, there are links in the video info.
